By anyone who takes booleans at face value (that is, takes booleans as
representing a truth value and expects operations on booleans to reflect
the semantics of useful operations on truth values, not some arbitrary
side-effect of the internal representation of a boolean...).

But I'm not surprised by such armchair commenting and pointless controversy
on python-ideas, since that's what the list is for....
