Your response here is fine (++), but I have just one comment:
"Perl may not be the most efficient solution..."
Efficiency is a very relative term. Efficient compared to what? Runtime? Compiling? Deploying? Developing?
I've been coding Perl since ~2001, and I assure you that unless you're doing Real Time type work (such as microcontroller business), Perl is pretty well efficient enough for almost all tasks, given enough CPU and memory (I'm speaking runtime here). When I code in C/C++ for a microcontroller, I almost always prototype in Perl first to get my ground ready, then do the lower level work. I can deploy anything in Perl (including 100% test coverage and full documentation), quicker than I could code, build and test anything in any other language, so there's that ;)
Also, I assure you that you will make more money if you get hired doing Perl, than you will in almost any other language at this time (that said, you've got to be damned good and experienced).
