I know you've asked for a *Perl* one-liner, but since a recent suggested
solution already "cheat" by using the shell to get the list of files, why not
just do it entirely in using standard command line programs ?

## prints the top 5 longest file names, remove the "r" from sort to print the
shortest.
ls | awk '{print length($0), $0}' | sort -nru | cut -f2 -d' ' | head -n5

Seems cleaner, and shorter than any Perl solution...
