This isn't the first time I've said this but also had an early-career job writing Perl code. And I actually got to the point where I liked it -- I mean I could see why it had a following.
Subsequently I've written code in almost every popular programming language and I will frequently go years between languages but even so I have very little trouble picking them back up. Even C++. But not Perl. It's just so weird with so many idiosyncrasies that I just can't remember it.
