So, in the situation where you have a countable number of parameters as the target of the sort, such as your example, or ($first, $second, $third, $fourth) = sort @ary; # only sort 4 entries @most[ 0 .. 6 ] = sort @ary; # only sort 7 entries the compiler could derive the hint, in a similar manner as it presently (recent feature) derives the in-place optimization. > * It'll make Randall Schwartz call my C coding "Amazing" which I can use on > the back covcer of my paperback If you put it on the back cover of your paperback, you might want to spell his name correctly. :) -- Glenn -- http://nevcal.com/ =========================== The best part about procrastination is that you are never bored, because you have all kinds of things that you should be doing.
