FYI: Haskell's OpenGL binding has just been dropped from GHC's extralibs, which means that it will no longer be kept in sync with GHC development, at least not by GHC HQ.
GHC HQ has its hands full and -generally speaking - extralibs are to be replaced by H(L)P, the Haskell (Library) Platform:
As someone who uses HOpenGL as a component for my own research, I must say that I don't entirely follow the logic of dropping it from extralibs. I mean, I fully appreciate that ghc-HQ wants to remove extralibs from its sphere of responsibility. And I also very much support the new Haskell Platform idea. But I did also get the impression that the HP was going to start from extralibs and build outwards. I can't see how dropping existing working and tested libraries from a mini-platform, is any help at all to the new maintainers of HP. It is only likely to give grief to users who expect HOpenGL to be part of HP, and then later more grief to the HP maintainers when they try to re-integrate it, after allowing it to suffer a period of bit-rot.
