When I read the quote from Guido speaking about code invariants, I
presumed that the internal code for `bool' uses things like:
if SUCH is True:
...
else:
...
relying on the facts that 1) if SUCH is true, than SUCH _is_ True, and
also, 2) that SUCH not being True means that it is necessarily False.
These surely allow for a simple and efficient `bool'.
