Looked into it in college. I liked it a lot - it's fast, clean, safe, and has some cool features. Also was easier to learn than Haskell.

I left it behind because it was easier to learn than Haskell. I use these languages (Ocaml, Haskell, Erlang, Scheme) because they're mind-expanding. For practical programs, I'd rather use something practical, like Python. Haskell was more mind-expanding than Ocaml, and so was better for the task at hand.
