typing: Add more tests for TypeVar ( #104571 )
...
During the PEP 695 implementation at one point I made
TypeVar.__name__ return garbage, and all of test_typing passed.
So I decided to add a few more tests. In the process I discovered
a minor incompatibility from the C implementation of TypeVar:
empty constraints were returned as None instead of an empty tuple.

- Compiler and interpreter changes to support the new syntax and scoping rules

The runtime implementation conveniently already exists in typing-extensions,

bpo-46581: Propagate private vars via _GenericAlias.copy_with (GH-31061)
...
GH-26091 added the _typevar_types and _paramspec_tvars instance
variables to _GenericAlias. However, they were not propagated
consistently. This commit addresses the most prominent deficiency
identified in bpo-46581 (namely their absence from
_GenericAlias.copy_with), but there could be others.
