Perl is not necessarily going to be attractive as a pedagogical language - partly because of TIMTOWDI. Also, there have been criticisms that Perl code is auto-obfuscated, which makes evaluation on pedagogical grounds challenging.

In my (limited) experience, Perl is used to get things done, and teaching languages are used for teaching. Perl exposure in academia is more likely to happen in the experimental sciences or occasionally in the Arts. If you are interfacing with telescopes, gathering data from sensor arrays or modelling bioinformatic systems, you'll likely hear about Perl before it would come up in CS.
