Yes, I’m very fond of trying out different languages. My main language for personal projects is Haskell.

I haven’t used J for a while, actually, but I recall finding it a bit confusing, especially when rank manipuations are involved. It has a larger vocabulary than most array languages, which I felt made it hard to learn. It was great fun though!
