It's also worth looking at Sort::Key which adds a nicer sorting syntax to Perl.

Instead of the usual:

@sorted = sort { uc $a cmp uc $b } @list;

You can just write:

@sorted = keysort { uc } @list;

You can even sort arrays in place:

keysort_inplace { uc } @list;
# And now @list itself is sorted. We don't
# need to create a new array called @sorted.
