short bit on languages

Go — awesome. Lack of support for “generics” kinda sucks. (list mapping sucks) []interface{} is useless sometimes. Damnit, I really just want a map function.
Haskell — lovely. Hard to get things to “just work” sometimes due to fun inherent in IO/monads.
OCaml — great. Haskell without the monad crap, but a crappier syntax. begin/end blocks uglify much. Try to go too functional and you run into the limitations of impurity.
