Hey!
In APIs that take a coroutine callbacks as a parameter, one would like to
make sure the callback given is in fact a coroutine. Partials are of course
useful in this scenario.
It occurs to me that `asyncio.iscoroutinefunction` should know about
coroutines wrapped in partials:
import
Usually you shouldn't be checking for couroutine functions directly. There
are too many cases where something returns in fact a coroutine but you
cannot tell by inspecting the thing you call -- you can only tell once
you've called it (using iscoroutine()). Partials are just one approach --
lambdas
