Short version:

- there are some reasonable requests for async variants of contextlib APIs for 3.7 - prompted by Raymond, I'm thinking it actually makes more sense to add these in a new asyncio.contextlib module than it does to add them directly to the existing module - would anyone object strongly to my asking authors of the affected PRs to take their changes in that direction? IMHO this is a good ideaiff the new APIs really are bound to asyncio, rather than being generic across all uses of async/await.

I agree. There is no need to make asynccontextmanager and AsyncExitStack dependent on asyncio or specific to asyncio.

They should both stay framework agnostic (use only protocols defined by PEP 492 and PEP 525) and both shouldn't be put into asyncio package.
