    He's asking for an async version of the 'iter' builtin, presumably
    something like:
    async def aiter(async_callable, sentinel):
       while True:
           value = await async_callable()
           if value == sentinel:
               break
           yield value
    -n

Yes, exactly (thanks, Nathaniel). Wouldn't that be a useful built-in?

Ah, sorry, I misunderstood.

I'm surprised this doesn't exist already -- it seems like an
obvious thing to have along with the other async features.
