Description
A suite of datatypes describing the (semi-concrete) abstract syntax of Haskell 98 http://www.haskell.org/onlinereport/ plus registered extensions, including:
- multi-parameter type classes with functional dependencies (MultiParamTypeClasses, FunctionalDependencies)
- parameters of type class assertions are unrestricted (FlexibleContexts)
foralltypes as universal and existential quantification (RankNTypes, ExistentialQuantification, etc)- pattern guards (PatternGuards)
- implicit parameters (ImplicitParameters)
- generalised algebraic data types (GADTs)
- template haskell (TemplateHaskell)
- empty data type declarations (EmptyDataDecls)
- unboxed tuples (UnboxedTuples)
- regular patterns (RegularPatterns)
- HSP-style XML expressions and patterns (XmlSyntax)
All nodes in the syntax tree are annotated with something of a user-definable data type. When parsing, this annotation will contain information about the source location that the particular node comes from.

AST nodes are annotated, and this class allows manipulation of the annotations.
Methods
Retrieve the annotation of an AST node.

Change the annotation of an AST node. Note that only the annotation of
the node itself is affected, and not the annotations of any child nodes.
if all nodes in the AST tree are to be affected, use fmap.
