I'll answer here for all the people who kindly answered.

Why would that be better than any(o.someattribute for o in someobjects) ? I think it's because lately I've been using common lisp a lot and the approach with the test function is pretty common there. Of course I already knew all the alternatives using map and the generator expression, but I felt like mine was clearer for a reader, this is probably true but not enough to justify the change.

I think that generator/list expressions are more common practice than
attrgetter/itemgetter, so I'm not even sure it's clearer.

I don't see the harm in a "key" argument like sorted has, but without
a key argument it could be extended to take more arguments like max/ min do for convenience. e.g. any(a, b, c) instead of any((a, b, c)).
