key argument for max?

I was wondering if there's any plans to add a "key" argument to max
(and min) like was done for sort(ed)? I fairly often run into a
situation where I have something like:
counts = {}
for item in iterable:
counts[item] = counts.get(item, 0) + 1
_, max_item = max((count, item) for item, count in counts.items())
It would be nice to be able to write that last like like:
max(counts, key=counts.__getitem__)
If this seems like a good idea, maybe someone could point me in the
right direction and I could try to make a patch? I've never looked at
the Python sources before, and it's been a long time since I've
written any C, but if it's not too hard...
