Is this any better? The true_for name does not satisfy me a lot...

Note that you don't need a list comp there:
>>> any([x for x in [1, 2, 3]])
True
>>> any([1, 2, 3])
True
so this may suffice:

Is there ever any advantage to having something as a builtin rather

it's a 2.5 addition. to use this in a "future-compatible" way in 2.3,
you can add
try:
any
except NameError:
def any(iterable):
for element in it
if any(instance.forbitToClose(archivefolder) for instance in
self.findActiveOutgoingRegistrationInstances())
Can you clarify where I can find "any"? It seems to me I'm unable to find it...
It's part of python2.5.
If you don't have that, you can write it your own and stuff it into
__builtins_
