/**
 * Brands a function as a directive factory function so that lit-html will call
 * the function during template rendering, rather than passing as a value.
 *
 * A _directive_ is a function that takes a Part as an argument. It has the
 * signature: `(part: Part) => void`.
 *
 * A directive _factory_ is a function that takes arguments for data and
 * configuration and returns a directive. Users of directive usually refer to
 * the directive factory as the directive. For example, "The repeat directive".
 *
 * Usually a template author will invoke a directive factory in their template
 * with relevant arguments, which will then return a directive function.
 *
 * Here's an example of using the `repeat()` directive factory that takes an
 * array and a function to render an item:
 *
 * ```js
 * html`<ul><${repeat(items, (item) => html`<li>${item}</li>`)}</ul>`
 * ```
 *
 * When `repeat` is invoked, it returns a directive function that closes over
 * `items` and the template function. When the outer template is rendered, the
 * return directive function is called with the Part for the expression.
 * `repeat` then performs it's custom logic to render multiple items.
 *
 * @param f The directive factory function. Must be a function that returns a
 * function of the signature `(part: Part) => void`. The returned function will
 * be called with the part object.
 *
 * @example
 *
 * import {directive, html} from 'lit-html';
 *
 * const immutable = directive((v) => (part) => {
 *   if (part.value !== v) {
 *     part.setValue(v)
 *   }
 * });

        //   until neither head nor tail can move.
        //
        // * Example below: keys at head pointers match, so update old
        //   part 0 in-place (no need to move it) and record part 0 in
        //   the `newParts` list. The last thing we do is advance the
        //   `oldHead` and `newHead` pointers (will be reflected in the
        //   next diagram).
        //
        //      oldHead v                 v oldTail
        //   oldKeys:  [0, 1, 2, 3, 4, 5, 6]
        //   newParts: [0,  ,  ,  ,  ,  ,  ] <- heads matched: update 0
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    and advance both oldHead

        //      newHead ^                 ^ newTail
        //
        // * Example below: head pointers don't match, but tail
        //   pointers do, so update part 6 in place (no need to move
        //   it), and record part 6 in the `newParts` list. Last,
        //   advance the `oldTail` and `oldHead` pointers.
        //
        //         oldHead v              v oldTail
        //   oldKeys:  [0, 1, 2, 3, 4, 5, 6]
        //   newParts: [0,  ,  ,  ,  ,  , 6] <- tails matched: update 6
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    and advance both oldTail
        //                                      & newTail
        //         newHead ^              ^ newTail
        //
        // * If neither head nor tail match; next check if one of the
        //   old head/tail items was removed. We first need to generate
        //   the reverse map of new keys to index (`newKeyToIndexMap`),
        //   which is done once lazily as a performance optimization,
        //   since we only hit this case if multiple non-contiguous
        //   changes were made. Note that for contiguous removal
        //   anywhere in the list, the head and tails would advance
        //   from either end and pass each other before we get to this
        //   case and removals would be handled in the final while loop
        //   without needing to generate the map.
        //
        // * Example below: The key at `oldTail` was removed (no longer
        //   in the `newKeyToIndexMap`), so remove that part from the
        //   DOM and advance just the `oldTail` pointer.
        //
        //         oldHead v           v oldTail
        //   oldKeys:  [0, 1, 2, 3, 4, 5, 6]
        //   newParts: [0,  ,  ,  ,  ,  , 6] <- 5 not in new map: remove
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    5 and advance oldTail
        //         newHead ^           ^ newTail
        //
        // * Once head and tail cannot move, any mismatches are due to
        //   either new or moved items; if a new key is in the previous
        //   "old key to old index" map, move the old part to the new
        //   location, otherwise create and insert a new part. Note
        //   that when moving an old part we null its position in the
        //   oldParts array if it lies between the head and tail so we
        //   know to skip it when the pointers get there.
        //
        // * Example below: neither head nor tail match, and neither
        //   were removed; so find the `newHead` key in the
        //   `oldKeyToIndexMap`, and move that old part's DOM into the
        //   next head position (before `oldParts[oldHead]`). Last,
        //   null the part in the `oldPart` array since it was
        //   somewhere in the remaining oldParts still to be scanned
        //   (between the head and tail pointers) so that we know to
        //   skip that old part on future iterations.
        //
        //         oldHead v        v oldTail
        //   oldKeys:  [0, 1, -, 3, 4, 5, 6]
        //   newParts: [0, 2,  ,  ,  ,  , 6] <- stuck: update & move 2
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    into place and advance
        //                                      newHead
        //         newHead ^           ^ newTail
        //
        // * Note that for moves/insertions like the one above, a part
        //   inserted at the head pointer is inserted before the
        //   current `oldParts[oldHead]`, and a part inserted at the
        //   tail pointer is inserted before `newParts[newTail+1]`. The
        //   seeming asymmetry lies in the fact that new parts are
        //   moved into place outside in, so to the right of the head
        //   pointer are old parts, and to the right of the tail
        //   pointer are new parts.
        //
        // * We always restart back from the top of the algorithm,
        //   allowing matching and simple updates in place to
        //   continue...
        //
        // * Example below: the head pointers once again match, so
        //   simply update part 1 and record it in the `newParts`
        //   array.  Last, advance both head pointers.
        //
        //         oldHead v        v oldTail
        //   oldKeys:  [0, 1, -, 3, 4, 5, 6]
        //   newParts: [0, 2, 1,  ,  ,  , 6] <- heads matched: update 1
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    and advance both oldHead
        //                                      & newHead
        //            newHead ^        ^ newTail
        //
        // * As mentioned above, items that were moved as a result of
        //   being stuck (the final else clause in the code below) are
        //   marked with null, so we always advance old pointers over
        //   these so we're comparing the next actual old value on
        //   either end.
        //
        // * Example below: `oldHead` is null (already placed in
        //   newParts), so advance `oldHead`.
        //
        //            oldHead v     v oldTail
        //   oldKeys:  [0, 1, -, 3, 4, 5, 6] <- old head already used:
        //   newParts: [0, 2, 1,  ,  ,  , 6]    advance oldHead
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]
        //               newHead ^     ^ newTail
        //
        // * Note it's not critical to mark old parts as null when they
        //   are moved from head to tail or tail to head, since they
        //   will be outside the pointer range and never visited again.
        //
        // * Example below: Here the old tail key matches the new head
        //   key, so the part at the `oldTail` position and move its
        //   DOM to the new head position (before `oldParts[oldHead]`).
        //   Last, advance `oldTail` and `newHead` pointers.
        //
        //               oldHead v  v oldTail
        //   oldKeys:  [0, 1, -, 3, 4, 5, 6]
        //   newParts: [0, 2, 1, 4,  ,  , 6] <- old tail matches new
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]   head: update & move 4,
        //                                     advance oldTail & newHead
        //               newHead ^     ^ newTail
        //
        // * Example below: Old and new head keys match, so update the
        //   old head part in place, and advance the `oldHead` and
        //   `newHead` pointers.
        //
        //               oldHead v oldTail
        //   oldKeys:  [0, 1, -, 3, 4, 5, 6]
        //   newParts: [0, 2, 1, 4, 3,   ,6] <- heads match: update 3
        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    and advance oldHead &
        //                                      newHead
        //                  newHead ^  ^ newTail
        //
        // * Once the new or old pointers move past each other then all
        //   we have left is additions (if old list exhausted) or
        //   removals (if new list exhausted). Those are handled in the
        //   final while loops at the end.
        //
        // * Example below: `oldHead` exceeded `oldTail`, so we're done
        //   with the main loop.  Create the remaining part and insert
        //   it at the new head position, and the update is complete.
        //

        //                     newHead ^ newTail
        //
        // * Note that the order of the if/else clauses is not
        //   important to the algorithm, as long as the null checks
        //   come first (to ensure we're always working on valid old
        //   parts) and that the final else clause comes last (since
        //   that's where the expensive moves occur). The order of
        //   remaining clauses is is just a simple guess at which cases
        //   will be most common.
        //
        // * TODO(kschaaf) Note, we could calculate the longest
        //   increasing subsequence (LIS) of old items in new position,
        //   and only move those not in the LIS set. However that costs
        //   O(nlogn) time and adds a bit more code, and only helps
        //   make rare types of mutations require fewer moves. The
        //   above handles removes, adds, reversal, swaps, and single
        //   moves of contiguous items in linear time, in the minimum
        //   number of moves. As the number of multiple moves where LIS
        //   might help approaches a random shuffle, the LIS
        //   optimization becomes less helpful, so it seems not worth
