+/**
+ * Overview:
+ *
+ * This module is designed to add support for an async `setValue` API and
+ * `disconnected` callback to directives with the least impact on the core
+ * runtime or payload when that feature is not used.
+ *
+ * The strategy is to introduce a `AsyncDirective` subclass of
+ * `Directive` that climbs the "parent" tree in its constructor to note which
+ * branches of lit-html's "logical tree" of data structures contain such
+ * directives and thus need to be crawled when a subtree is being cleared (or
+ * manually disconnected) in order to run the `disconnected` callback.
+ *
+ * The "nodes" of the logical tree include Parts, TemplateInstances (for when a
+ * TemplateResult is committed to a value of a ChildPart), and Directives; these
+ * all implement a common interface called `DisconnectableChild`. Each has a
+ * `_$parent` reference which is set during construction in the core code, and a
+ * `_$disconnectableChildren` field which is initially undefined.
+ *
+ * The sparse tree created by means of the `AsyncDirective` constructor
+ * crawling up the `_$parent` tree and placing a `_$disconnectableChildren` Set
+ * on each parent that includes each child that contains a
+ * `AsyncDirective` directly or transitively via its children. In order to
+ * notify connection state changes and disconnect (or reconnect) a tree, the
+ * `_$notifyConnectionChanged` API is patched onto ChildParts as a directive
+ * climbs the parent tree, which is called by the core when clearing a part if
+ * it exists. When called, that method iterates over the sparse tree of
+ * Set<DisconnectableChildren> built up by AsyncDirectives, and calls
+ * `_$notifyDirectiveConnectionChanged` on any directives that are encountered
+ * in that tree, running the required callbacks.
+ *
+ * A given "logical tree" of lit-html data-structures might look like this:
+ *
+ *  ChildPart(N1) _$dC=[D2,T3]
+ *   ._directive
+ *     AsyncDirective(D2)
+ *   ._value // user value was TemplateResult
+ *     TemplateInstance(T3) _$dC=[A4,A6,N10,N12]
+ *      ._$parts[]
+ *        AttributePart(A4) _$dC=[D5]
+ *         ._directives[]
+ *           AsyncDirective(D5)
+ *        AttributePart(A6) _$dC=[D7,D8]
+ *         ._directives[]
+ *           AsyncDirective(D7)
+ *           Directive(D8) _$dC=[D9]
+ *            ._directive
+ *              AsyncDirective(D9)
+ *        ChildPart(N10) _$dC=[D11]
+ *         ._directive
+ *           AsyncDirective(D11)
+ *         ._value
+ *           string
+ *        ChildPart(N12) _$dC=[D13,N14,N16]
+ *         ._directive
+ *           AsyncDirective(D13)
+ *         ._value // user value was iterable
+ *           Array<ChildPart>
+ *             ChildPart(N14) _$dC=[D15]
+ *              ._value
+ *                string
+ *             ChildPart(N16) _$dC=[D17,T18]
+ *              ._directive
+ *                AsyncDirective(D17)
+ *              ._value // user value was TemplateResult
+ *                TemplateInstance(T18) _$dC=[A19,A21,N25]
+ *                 ._$parts[]
+ *                   AttributePart(A19) _$dC=[D20]
+ *                    ._directives[]
+ *                      AsyncDirective(D20)
+ *                   AttributePart(A21) _$dC=[22,23]
+ *                    ._directives[]
+ *                      AsyncDirective(D22)
+ *                      Directive(D23) _$dC=[D24]
+ *                       ._directive
+ *                         AsyncDirective(D24)
+ *                   ChildPart(N25) _$dC=[D26]

+ *                      AsyncDirective(D26)
+ *                    ._value
+ *                      string
+ *
+ * Example 1: The directive in ChildPart(N12) updates and returns `nothing`. The
+ * ChildPart will _clear() itself, and so we need to disconnect the "value" of
+ * the ChildPart (but not its directive). In this case, when `_clear()` calls
+ * `_$notifyConnectionChanged()`, we don't iterate all of the
+ * _$disconnectableChildren, rather we do a value-specific disconnection: i.e.
+ * since the _value was an Array<ChildPart> (because an iterable had been
+ * committed), we iterate the array of ChildParts (N14, N16) and run
+ * `setConnected` on them (which does recurse down the full tree of
+ * `_$disconnectableChildren` below it, and also removes N14 and N16 from N12's
+ * `_$disconnectableChildren`). Once the values have been disconnected, we then
+ * check whether the ChildPart(N12)'s list of `_$disconnectableChildren` is empty
+ * (and would remove it from its parent TemplateInstance(T3) if so), but since
+ * it would still contain its directive D13, it stays in the disconnectable
+ * tree.
+ *
+ * Example 2: In the course of Example 1, `setConnected` will reach
+ * ChildPart(N16); in this case the entire part is being disconnected, so we
+ * simply iterate all of N16's `_$disconnectableChildren` (D17,T18) and
+ * recursively run `setConnected` on them. Note that we only remove children
+ * from `_$disconnectableChildren` for the top-level values being disconnected
+ * on a clear; doing this bookkeeping lower in the tree is wasteful since it's
+ * all being thrown away.
+ *
+ * Example 3: If the LitElement containing the entire tree above becomes
+ * disconnected, it will run `childPart.setConnected()` (which calls
+ * `childPart._$notifyConnectionChanged()` if it exists); in this case, we
+ * recursively run `setConnected()` over the entire tree, without removing any
+ * children from `_$disconnectableChildren`, since this tree is required to
+ * re-connect the tree, which does the same operation, simply passing
+ * `isConnected: true` down the tree, signaling which callback to run.
