[New-bugs-announce] [issue46581] _typevar_types and _paramspec_tvars are missing from _GenericAlias.copy_with

[Matt B]

New submission from Matt B <eb3f73+python+org at yaymail.com>:

c55ff1b352f8b82184f80d9dea220e832691acfc was submitted to fix #44098 and added the _typevar_types and _paramspec_tvars properties to _GenericAlias. However, those properties continue to be omitted from _GenericAlias.copy_with[1].

Further, typing.py is fairly intricate, which makes it hard to understand if that is the only place those properties are absent. A more careful review/audit may be in order.
