An acronym, are you sure? Perlfaq1 - What's the difference between "perl" and "Perl"?:

"You may or may not choose to follow this usage. For example, parallelism means "awk and perl" and "Python and Perl" look good, while "awk and Perl" and "Python and perl" do not. But never write "PERL", because perl is not an acronym, apocryphal folklore and post-facto expansions notwithstanding."

I doubt telling someone this, and that they've posted in the wrong section is enough to stop someone adopting a programming language.
