Right... Having two differently implemented versions of Object[].Sort() (one
which behaves efficiently when not given an optional argument and one which
passes that argument) is, if not an insane interface, at least nothing that
belongs to the gb component.
For our purposes, maybe a small component gb.multisort may suffice which
enhances Object[] by the necessary logic and we would require users to
provide a _compare2() then which could take the additional argument. No
big deal.
