The `inspect.iscoroutinefunction` and `inspect.iscoroutine` functions return `False` for the `asend`, `athrow` and `aclose` methods of asynchronous generators (PEP 525). These are coroutine functions (i.e. one does e.g. `await gen.asend(value)`) so I would have expected these to return `True`.


async def generator():

>>> import inspect
>>> g = generator()
>>> inspect.iscoroutinefunction(g.asend)

>>> inspect.iscoroutine(g.asend(None))
