João Bernardo <jbv...@gmail.com> added the comment: The problem with `not in` is because it must evaluate the result. It's not just another operator like "==" and "!=".
Looks like we're suffering from premature optimization and now it would break a lot of code to make it good. For my application, I created a different method to generate the object (Not as good as I wanted, but there's no option right now): `MyClass().has(1)` instead of `1 in MyClass()` So, if no one comes up with a better idea, this issue should be closed.
