what is your excuse for not using OCAML?

it's blazing fast. strict (not like the other shit), french.

it supports:
  functional style (yay)
  imperative programing (because mutation is essential)
  and a sane OOP (seriously is one sane OOP, is not ambitious is just useful)

pattern matching is great. i would love to see a OS with it's entire userland written in this.

but i don't why haven't catch on?, what is your excuse Prog

It's my favorite language. It just makes so much sense both practically and in terms of beauty and clarity. Just too bad there is so little code (as in libraries) out there in it. I try to use it as much as possible but since there are no libraries and stuff, that means I use it to code up stand alone programs that do some simple little thing. Pretty much forced to use Matlab now due to my research. Only other option is C++ and I can't stand C++. Well also python, but can't stand that either.
