For now I can use mix asyncio.coroutines and `async def` functions, I

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,
