[Python-Dev] Any reason that any()/all() do not take a predicate argument?

sorry if this came up before, but I tried searching the archives and
found nothing. It would be really nice if new builtin truth functions
in 2.5 took a predicate argument(defaults to bool), so one could
write, for example:
seq = [1,2,3,4,5]
if any(seq, lambda x: x==5):
which is clearly more readable than
reduce(seq, lambda x,y: x or y==5, False)
IIRC, something like that is called junctions in Perl 6.
