[New-bugs-announce] [issue38424] typing.Generator shorthand

[Dima Tisnek]

New submission from Dima Tisnek <dimaqq at gmail.com>:

Currently to annotate a generator, something like `Generator[str, None, None]` is required. Which is a bit confusing and verbose.

Can we allow shorthand, like `Generator[str]` for simple cases?

I'm not entirely certain what the semantics ought to be...
Maybe Generator[t1, t2=Any, t3=None] ?
