In this case, the two lines "fnc" and "next" simply look up the

Which is actually useful. I've got some 2.4 code that reads
try:
any
except NameError:
def any(...):
...
(with a similar block for all() )
I don't want to call any() or all(), I simply want to test whether
they exist.
But would it have been much of an imposition to have typed:
try:
test = any
except NameError:
def any(...):
...
? (Or any of the half dozen ways there must be to test the existence of
a name.)
