Andrew,

For now I can use mix asyncio.coroutines and async def functions, I mean I can write await f() inside async def to call asyncio.coroutine f and vise versa: I can use yield from g() inside asyncio.coroutine to call async def g(): ....

That's another good point that I forgot to add to the list. Thanks for bringing this up.

If we forbid to call async def from regualr code how asyncio should work? I'd like to push async def everywhere in asyncio API where asyncio.coroutine required.

You'll have to use a wrapper that will do the following:

async def foo(): return 'spam'

@asyncio.coroutine def bar(): what = yield from foo.await(foo, *args, **kwargs) # OR: what = yield from await_call(foo, *args, **kwargs)

Thanks, Yury
