I have recently changed jobs, in my old job - I used PERL because I wanted to. In my new job I use PERL because I have too. I haven't had to re-learn perl per say, but rather how to code perl for a community rather than just for myself ie easier to read, and more efficient. Its been a trying process, but a worth while endeavor. Iv'e been using PERL for a number of years and have learned to better utilize the tools PERL has to offer, and some features that I never even knew existed.
