// (floordiv) isn't equivalent to a multiplication, but it is also at the same level. << and >> aren't inverses, but they are at the same level. 'in' and 'is' are not even the same type (they have totally different requirements on their right argument) but they are at the same level. Whatever choice we make needs to be something we can justify, and our justification should probably not imply that all of python's other operators are wrong ;-).
