Added
__getitem__
for_CallableGenericAlias
so that it returns a subclass (itself) oftypes.GenericAlias
rather than the default behavior of returning a plaintypes.GenericAlias
. This fixesrepr
issues occuring afterTypeVar
substitution arising from the previous behavior.https://bugs.python.org/issue42195
