Do we want to keep using this definition of map on the new vectors? As I understand it, map on ~[T] is considered deprecated for a long time, as iterators allow one to express the same, and if we ever get Iterable it would conflict anyway.

If it makes landing the ~[] removable easier, keep it: someone else can remove it later if necessary.
