NameError: name 'M' is not defined
Although get_type_hints does not work with imported imported type aliases, this is not imported, so I would expect it to work. Further, the documentation for the function indicates using PEP 563 should /help/, but in this case it actually causes an error.

FWIW, removing the PEP 563 import works fine, giving:
