I would strongly suggest using Getopt::Long. It takes all the headaches out of processing command-line parameters. I'd go as far as saying that if you're processing a command-line, and you want to do anything other than accept a plain old list of filenames, then you're a fool not to use it. Unless of course, that would be disallowed by the guidelines for your assignment.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
