Nimrod's builtin slices copy. It's possible to implement more

By the way, current enums can be modified to correspond list

I think D enums need to become a bit more strict (so you can't
equal elements of different enums).
Pascal got type safe enums and sets of enums (aka flags) right
in the 60ies. Too bad not even Ada copied this nice feature.
