This is purely anecdotal, but learning Perl is currently on my backburner in part due to its reputation. I did use it a bit in a bioinformatics class, and I have edited a few small Perl scripts, but Python simply works for me. Perl's reputation, if you could call it that, has negatively impacted my desire to learn the language.

(Maybe I'm worse off for it? Who knows. I mean no harm and don't want to impinge on anyone's feelings. I just don't see myself picking up Perl anytime soon. Just my own two cents, FWLIW.)
