Haskell-Source with Extensions (HSE, haskell-src-exts) is an extension
of the standard haskell-src package, and handles most registered
syntactic extensions to Haskell, including:

    * Multi-parameter type classes with functional dependencies
    * Indexed type families (including associated types)
    * Empty data declarations
    * GADTs
    * Implicit parameters
    * Template Haskell 

and a few more. All extensions implemented in GHC are supported. Apart
from these standard extensions, it also handles regular patterns as per
the HaRP extension as well as HSX-style embedded XML syntax.
