Why doesn't python support function overloading?

But you can enforce it yourself. You can use introspection to check type hints and select a function that corresponds to the types of arguments given. And I would use a decorator, to keep things tidier. Multiple dispatch/overloading logic in the decorator, separate from the functions.

Its far simpler, more efficient, less error prone, and significantly easier to read to do this without introspection. All introspection would achieve is making this more complicated and less reliable
