Yes, exactly. We would begin by providing the hint for the simple cases
and gradually exapnd the range of optimized situations . I
imagine a working intermediate stage where your first example is
optimized and your second is not, but maybe the second is already
optimized to
($most[0],$most[1],$most[2],$most[3],$most[4],$most[5],$most[6]) = ...
at some level, in which case we could get them both at the same time.
