/**
* A directive that renders the items of an async iterable[1], replacing
* previous values with new values, so that only one value is ever rendered
* at a time. This directive may be used in any expression type.
*
* Async iterables are objects with a `[Symbol.asyncIterator]` method, which
* returns an iterator who's `next()` method returns a Promise. When a new
* value is available, the Promise resolves and the value is rendered to the
* Part controlled by the directive. If another value other than this
* directive has been set on the Part, the iterable will no longer be listened
* to and new values won't be written to the Part.
*

*
* @param value An async iterable
* @param mapper An optional function that maps from (value, index) to another
* value. Useful for generating templates for each item in the iterable.
