I'm in the process of changing jobs. I'm currently working at a huge company (~60.000 employees) and here I'm working in Python. I don't think Python is a bad language, but some things it feels a bit weird and I actually prefer Perl. So now I'm joining a startup (not that small, about 80 people) and there I'll be working in Perl. In this startup Perl is used for test automation, where I think it's a really strong language.

So this is just a personal anecdote that there are still startups out there that start using Perl. And from my previous experience (moving from a Perl background to a Python job) I really wouldn't be afraid of sticking with Perl. The switch to another language isn't that hard (if you have to do it at some point because your new job requires it) and all companies I interviewed with never saw this as a problem.
