Oh, and ranges themselves get copied all over the place, so if someone is foolish enough to make copying _them_ expensive, they're screwed. Of course, if someone actually made a range deep copy with a postblit, that would also violate the logic of how ranges even work, but it's an example of a type that gets copied a lot, and if copying it were expensive, then performance would probably tank. - Jonathan M Davis
