in reply to Is it worth knowing Perl? Real-life examples please
It is always a good idea to pick up proficiency in yet another programming language, because these are the tools of your trade. You simply never know what already-entrenched language you will be asked to work with next ... or, how many. I am currently working with a client who is simultaneously using Perl, PHP, and Python, with a fair amount of RPG, and that is not particularly unusual. Time that you spend self-learning will usually pay off someday when you least expect it.
