[New-bugs-announce] [issue46589] Improve documentation for typing._GenericAlias

[Matthew Rahtz]

New submission from Matthew Rahtz <matthew.rahtz at gmail.com>:

There's currently not much documentation in `typing.py` for `_GenericAlias`. Some fairly weird things go on in there, so it would be great to have more info in the class about what's going on and why various edge cases are necessary.
