Haskell Source Extensions

haskell-src-exts is a package for handling and manipulating Haskell source
code. It is a descendant of the haskell-src package that is part of the standard
libraries, but extends this to support a number of syntactic
extensions, e.g. MPTCs, fundeps, GADTs, TH etc. The aim is to support all
extensions recognized by the community, as determined by what is implemented
in compilers and tools.

Apart from the more standard extensions supported by e.g. GHC,
haskell-src-exts provides support for HaRP (Haskell Regular Patterns)
and HSX (Haskell Source with XML) syntax.

Package structure

The modules that comprise haskell-src-exts all reside in the hierarchic
namespace Language.Haskell.Exts, or its more feature-rich sibling
Language.Haskell.Exts.Annotated. Notable exposed modules include:
