No, there must be an implementation (or make this in a .pyi file in test).

This is not how overloads work. PEP 484:
In regular modules, a series of
@overload-decorated definitions must be followed by exactly one non-@overload-decorated definition

OK, sorry. I will add one.

It would be nice to have a few more test cases:
- Test two overload variants which have two different metaclasses as argument types, and overloading based on metaclass.
- Test calling the overloaded function with a
strargument (results should bestr).
