 GHC is a state-of-the-art, open source, compiler and interactive environment

 - GHC compiles Haskell code either directly to native code or using LLVM

   porting to new platforms. The interactive environment compiles Haskell to
   bytecode, and supports execution of mixed bytecode/compiled programs.
