Yes, it's a 2.5 thing. All returns true if all of the elements of an
iterable are true. According to the docs, it is the equivalent of the
following:
def all(iterable):
for element in iterable:
if not element:
return False
return True
Using 'all' with a generator expression has the virtue of only needing
to look at the string until it finds a single element that is false,
and then returning. Not only that, it's concise (a single line) and
quite readable (at least to me).
