…ules This makes the default behavior (without specifying `globalns` manually) more predictable for users, finds the right globalns automatically. Implementation for classes assumes has a `__module__` attribute and that module is present in `sys.modules`. It does this recursively for all bases in the MRO. For modules, the implementation just uses their `__dict__` directly. This is backwards compatible, will just raise fewer exceptions in naive user code. Originally implemented and reviewed at python/typing#470.
