%description
Write sequential-looking code that pauses and resumes. gen() creates a
generator, an iterator that returns a value and pauses each time it
reaches a yield() call. async() creates a promise, which runs until it
reaches a call to await(), then resumes when information is available.
These work similarly to generator and async constructs from 'Python' or
'JavaScript'. Objects produced are compatible with the 'iterators' and
'promises' packages. Version 0.3 supports on.exit, single-step debugging,
stream() for making asynchronous iterators, and delimited goto() in
switch() calls.
