[Haskell-cafe] The Layout Rule

I am looking for background material on how GHC and other Haskell
compilers implement the layout rule.  Are there any papers,
documentation, commentary, etc. that discus the actual implementation
of this rule (even if only a paragraph or two)?

I've already looked at the parsing code in GHC and UHC.  Do any other
Haskell compilers have interesting approaches for implementing the
layout rule?

I am writing a paper about a new formalism for indentation sensitive
languages and I want to ensure I've covered the appropriate background
material on existing implementations of the layout rule.
