I understand that you would expect the same result when calling a function on a list and on a tuple. I'm still not sure it needs to be changed: what you call a bug is obviously a feature for many people.
And nevertheless, what I don't see is why you would expect the same behaviour when calling () or [ ] on a object. Yes, maybe, it wasn't the best choice. But it's not absurd: it just considers the permutation to be a word and adds the () feature to use it as a function. Changing this would just mess tons of people work, mine included. But anyway we're going very far from the original subject. I'm not sure anyone has time now to rethink permutations entirely in a way that would be more consistent and without messing people's code and work, i.e. without erasing everythink as you suggest and change behaviour everywhere on a object that is used by many many people.
