Yes. That example looks particularly good.
Somebody emailed me privately with a poster-child for this technique, which,
now that I've been reminded, I *do* use ("locally" applies strongly here):
def f(a):
a = int (a)
# ...
or, in a slightly different context:
class ThisClass (object):
# ...
def __add__ (self, other):
if not isinstance (other, ThisClass):
other = ThisClass (other)
