Hi Michael,

I am looking for background material on how GHC and other Haskell
compilers implement the layout rule.
In the context of our work on syntactic extensibility, we have
implemented a declarative and extensible mechanism to specify and
implement layout rules. A paper about the approach is currently under
review, and a draft is available [1]. The implementation and evaluation
data is available [2].

We used our parser in the implementation of SugarHaskell, a
syntactically extensible variant of Haskell. A paper about SugarHaskell
is currently under review, and again, a draft is available [3].
The implementation can be installed as an Eclipse plugin from the SugarJ
website [4]. A command-line version is forthcoming.
