Exactly. The async function/method is an implementation technique for a
specific kind/subset of coroutine functionality. So the term coroutine,
qualified by a description of its best usage and limitationsof async
function, can be used in defining async function, thus appealing to what
people know or have heard of and vaguely understand and can read more
about in the literature.
A glossary entry for coroutine in the docs seems appropriate, which
could point out the 16† ways to implement coroutine-style
functionalities in Python, and perhaps make recommendations for
different types of usage.
†OK, not 16 ways, but it is 3 now, or 4?
