[Haskell] Monads in Perl

Hopefully this isn't too far off topic. In my quest for monad understanding, I decided that it would be helpful if I translated Haskell code examples into a language I had a better understanding of. I ended up choosing Perl, and I decided to write up an article with my findings, in the hope of helping other newbies. FWIW, you can read it at... http://sleepingsquirrel.org/monads/monads.html (every true haskell hacker has to write at least one monad tutorial right?) If anyone has any questions/comments/suggestions, I'd be interested in hearing them. Thanks, Greg Buchholz
