We built SugarHaskell to explore that design space. See our paper at the
Haskell Symposium 2012:
While there is not much going on about SugarHaskell specifically, the
underlying language-independent framework is still actively developed,
in the https://github.com/sugar-lang organization. The eclipse plugin
for SugarHaskell from http://update.sugarj.org/ should work. I don't
know what the status of the command-line version is, though.
Even if you don't want to use all of SugarHaskell, the underlying easily
extensible grammar might still be a good starting point. It uses
declarative layout constraints to specify Haskell's layout in a modular
way. See our paper at the conference on software language engineering 2012:
