haskell
Haskell-Source with eXtensions (HSX, haskell-src-exts) is an extension of the
standard haskell-src package, and handles most common syntactic extensions to
Haskell, including:
* Multi-parameter type classes with functional dependencies
* Empty data declarations
* GADTs
* Implicit parameters (ghc and hugs style)
* Template Haskell (broken for 6.4, needs redoing)
