I've done some experiments with grammar, and it looks like
we indeed can parse await quite differently from yield. Three
different options:
You don't seem to have tried what I suggested, which is
to make 'await' a unary operator with the same precedence
as '-', i.e. replace
factor: ('+'|'-'|'~') factor | power
with
factor: ('+'|'-'|'~'|'await') factor | power
That would allow
await a()
res = await a() + await b()
res = await await a()
if await a(): pass
return await a()
print(await a())
func(arg=await a())
await a() * b()
