1) it's not like people commonly alias "repr()" or "len()", so why would
they alias an "await()" builtin ? Unless, obviously, there's an actual
reason to do so, in which case having it as a functions comes in handy. :)
We had the same line of reasoning with "print()" back in the days of Py3k.

2) an "await()" builtin function that calls an "__await__()" special method
on its input object sounds very pythonic.
