[issue41967] Handle annotations in the parser to avoid the need for roundtrip

[Guido van Rossum]

Guido van Rossum <guido at python.org> added the comment:

Hm, this buffer thing is not what I had expected. I think it's a show-stopper -- if we don't reproduce spaces exactly.

Maybe we should just buffer the entire input always?

A way to handle multi-line annotations would be to surround them with parentheses? That way get_type_hints() doesn't need to change. Alternatively, strip comments and newlines in get_type_hints().
