/**
 * The async function is a decorator for generator functions, turning

 * Firefox/Spidermonkey, however, this code does not cause syntax
 * errors in older engines.  This code should continue to work and
 * will in fact improve over time as the language improves.
 *
 * Decorates a generator function such that:
 *  - it may yield promises
 *  - execution will continue when that promise is fulfilled
 *  - the value of the yield expression will be the fulfilled value
 *  - it returns a promise for the return value (when the generator
 *    stops iterating)
 *  - the decorated function returns a promise for the return value
 *    of the generator or the first rejected promise among those
 *    yielded.
 *  - if an error is thrown in the generator, it propagates through
 *    every following yield until it is caught, or until it escapes
 *    the generator function altogether, and is translated into a
 *    rejection for the promise returned by the decorated generator.
 *  - in present implementations of generators, when a generator
 *    function is complete, it throws ``StopIteration``, ``return`` is
 *    a syntax error in the presence of ``yield``, so there is no
 *    observable return value. There is a proposal[1] to add support
 *    for ``return``, which would permit the value to be carried by a
 *    ``StopIteration`` instance, in which case it would fulfill the
 *    promise returned by the asynchronous generator.  This can be
 *    emulated today by throwing StopIteration explicitly with a value
 *    property.

 *
 *  - has an intermediate representation to allow processing of parsed data (We

 *
 *  - is easily extensible to add new dialects without having to rewrite the
 *    entire parsing mechanics
 *
 *  - has a good test suite
 *
 *  This implementation fulfills all of these (except that the test suite could
 *  do with expanding to automatically run all the fixtures from other Markdown
