You can override a comparison operator which means it’s potentially unbounded (not simple) exactly the same way as matching is.

but

1) it's "opt in" (you need to explicit implement the dunder method) and

2) it's only for specific classes, you cannot change the behavior of 1 == "one"

But you can't do that for pattern matching either.

More clearly because builtins are protected from monkey-patching, you can’t change the behavior of == where both operands are builtins. “Only for specific classes” implies the scope of applicability is much narrower than it is.
