Most of my career since 1996 has been in developing Perl. I'm a contractor who gets hired (and paid well) to help with Perl projects. By no stretch can you say I "rarely use it".

And I still consider Perl one of the more difficult languages to deal with because it's very easy to rely on implicit behaviour that - whilst perfectly clear as you develop it - makes life inordinately hard a year later when you're trying to debug an edge case because now, e.g., people can have two different delivery methods in the same basket (whoops, the second one overwrote the first one in the hash!)
