I think that we are better off using the same names as in EiffelBase.
EiffelBase uses `do_all' and `do_all_with_index'. I think that
`do_all_with_key' follows this pattern.

Also, if in linear we had `for_each' which gets the items, I would
not want that name to be changed to `for_each_item' in tables
or in arrays (so that `for_each' could now, inconsistently, get
items and keys in tables or items and indexes in arrays).
