yes, that's a good place to start.
but, just because i like being different and because i really enjoy
the power of this simple little module:
perl -e 'use List::UtilsBy qw/sort_by/; @arr = qw/4 5 3 6 2/; @sorted
= sort_by { $_ } @arr; print "@sorted\n";'
oh, and because LeoNerd wrote it and because it does what you want
with less typing :)
