OCaml was like meeting an old and forgotten friend. I found its syntax a bit clunky, but could get accustomed to it. Its list matching is nice, O(n) list element accessing, not so much. Honestly, I wanted to really like it, but I'm not sure yet. And it's *slow* compared to C. OCaml was like meeting an old and forgotten friend.
