Can you overload the match operator?

Question

There are many operators in python that can be overloaded (like +). But going through the docs for python 3.10 and PEP 622, I was wondering whether the same can be done for the match operator (e.g. to simplify an object's representation) - or would this be done through the __match_args__ attribute?

Can you overload the match operator?

The short answer is No.

The logic for Structural Pattern Matching is hardwired into the grammar of the language. The only method hook is __match_args__ which is only used to give field names for positional arguments in the class pattern.
