I learned it in my "Programming Languages" class in university. And then about 6 months later I had completely forgotten it. It's one of those things you need to use regularly to keep it in memory. At least that's the case for me. I tend to shy away from it these days for a lot of cases (ever try to regex validate an email??) but when I do use it I it's honestly just a process of re-learning for about 15 minutes each time.
