We had a huge discussion of this stuff when bools were introduced
in Python 2.3 or thereabouts.  The current system is about the
best way that doesn't break everything in sight.  The weirdness
is basically a consequence of bools being an afterthought in Python.
Python has a long tradition of implicitly casting other values to
bool, e.g. strings, lists, sets etc. are all false if empty, etc.
