I'd use it if I knew how <shrug>.

It's easy. After starting your script with "perl -d script.pl", there's only 3 commands. One of them is "q" to quit[1]. Next is "n", to go the next line of your code. Repeat until problem found. Last comes "x" to display data structures.

Yes, print Dumper( $foo ) statements liberally sprinkled around are easier.

Yes, there's breakpoints and all that guff, but if you want that, RTFM.
