Does this work if the implementation function is called like the first decorated function?

No, the register() attribute returns the undecorated function which enables decorator stacking, as well as creating unit tests for each variant independently.

Making generic functions work with ABCs sounds like a requirement to me

Yes, I will implement that.

Question: what happens if two functions (say in two different modules) are registered for the same type?

Last one wins. Just like with assigning names in a scope, defining methods in a class or overriding them in a subclass.
