Dirty, dirty trick :-).

`assert' is quite useful in its real and genuine purpose.  There is
something heretic in allowing side effects in `assert' statements.  A
few centuries ago, Python programmers doing this were burnt in public,
and this is how Python got forgotten for so long.  (Guido rediscovered
it a dozen years ago, the wise guy attributed all the merit to himself!)
