[issue47006] PEP 646: Decide on substitution behavior

[Matthew Rahtz]

Matthew Rahtz <matthew.rahtz at gmail.com> added the comment:

P.s. To be clear, (I think?) these are all substitutions that are computable. We *could* implement the logic to make all these evaluate correctly if we wanted to. It's just a matter of how much complexity we want to allow in typing.py (or in the runtime in general, if we say farmed some of this logic out to a separate module).
