Haskell. I lost my enjoyment for programming. I wrote very little code for about 5 years after burning out. One of my friends wanted to do a joint coding project and he suggested Haskell, so I solved one or two hundred project Euler problems in Haskell. I never got good at Haskell, but I really do enjoy writing smaller projects (less than 5,000 lines of code) in Haskell. Haskell inspired me to read two fairly easy books on Category Theory. I really enjoyed that also. I still don't write a lot of code. Every few months, there will be a problem at work that needs my help and then I write the equivalent of 3000 lines of C++. Or, there will be a math problem that I want to solve on the computer. I really enjoy writing those shorter, self-contained programs. (PS: I started writing code in 1980.)
