Doesn't len() have a requirement that __len__ return an integer? If so,
perhaps it would be better if this were:
def bool(obj):
try:
return obj.__bool__()
except AttributeError:
return len(obj) > 0
If I'm wrong (don't have the source available right now) then perhaps
len() *should* have this requirement.
