      In this python-ideas thread it was suggested to create a public API for typing._eval_type in order to be able to create custom versions of get_type_hints. Specifically a version that allows to specify an upper boundary in the MRO when retrieving type hints for a class object.

      The public API should use None as defaults for globalns and localns and not expose the recursive_guard parameter.
