OCaml

What do you think of OCaml?

Right now it's my favorite language. It's actually practical and fast (unlike Haskell). Also I can use imperative style whenever I feel like it but I still have all of the goodness from using a functional language. I am starting to use it as my regular language.

C/C++ has an excellent module system and it has functors. Functors are basically functions that map modules to modules.
