I don't see why: you can easily synthesize that with map/imap.

So write
any(map(operator.attrgetter('some_attribute'), some_objects))
# same number of characters to type
any(o.some_attribute for o in some_objects)
# fewer number of characters

So write
all(map(some_objects, zerop))
or
all(o==0 for o in some_objects)
# avoids defining zerop

What is the disadvantage of such "preprocessing"?
