Naming #75
Description
Bike shedding time!
Are the names Copy, Insert, Remove, Change based on some convention?
I find Copy confusing - to me it sounds like maybe an element has been duplicated, as in diff([A], [A, A]) would yield [Copy(0), Copy(0)] or something like that. Maybe Identical or Same is a better name?
Change also seems a bit generic. Replace sounds better to my ears.
