I noticed that collections.Counter, unlike set, doesn't support the ordered comparison operators (> < >= <=). I'd like to propose implementing these operators in an analogous fashion to set: counter1 >= counter2 if counter1 contains at least as many of every key as counter2 does. Cases where counter1 doesn't have a key and counter2 has a negative amount of that key would still count as >=. counter1 > counter2 when counter1 >= counter2 and counter1 != counter2.
Does this sound reasonable? If so I'll write up and submit a patch. - Kerrick
