This is precisely why I now think that the proposed formalization of
Python truth value system should not be called 'bool'.  Too many
people expect it to be like it "should' be, rather that how it was
designed.  Python truth values, like, for instance, Python lists, were
designed on a pragmatic basis without necessarily being constrained by
other similar models.
