How is it any different from grammatically requiring
parens in an ordinary function call? Nobody ever
complained about that.
It is different.
1. Because 'await' keyword might be at a great distance
from the object you're really calling:
await foo.bar.baz['spam']()
+-----------------------+
Can I chain the calls:
await foo()() ?
or await foo().bar()?
2. Because there is no other keyword in python
with similar behaviour.
3. Moreover: unless I can write 'await future' - your
proposal *won't* work with a lot of existing code
and patterns. It's going to be radically different
from all other languages that implement 'await' too.
