I've recently been 'downsized' from a job where I've been developing in C++ (great time to lose a job, Christmas), and I've decided to spend my time 'between' jobs becoming re-acquainted with perl. The problem is I haven't done any perl development for about 3 years now, and I wasn't particularly a rocket scientist back then. It is amazing how much of this stuff you lose if you don't use it everyday.

I've dragged my camel book down from the shelf and started working through it again, but what I really need is to somehow dredge all the knowledge I used to have back out of the depths of my memory.

Has anyone else been in this situation when they needed to relearn a language? If so, how did you go about?
