I am using the haskell-src bundle to implement a preprocessor for some syntactic extensions to haskell. This is all fine and well, but I find myself also wanting the preprocessor to let through some already existing extensions, namely:
* implicit parameters
* pattern guards
* multi-parameter type classes with functional dependencies
* possibly template haskell
The haskell-src bundle already has support for mptcs (without fundeps), and pattern guards are rather straight-forward, but for the rest;
Where can I find formal specifications of these extensions in terms of added/changed syntax?
Or even better, is there anyone out there who has already extended the haskell-src bundle with support for any of them?
