	I can see its usefulness for development of a family
	of some compiler-independent, light-weight utilities for
	Haskell, operating on sources of Haskell modules:
 
	+ Converter from literate to non-literate source code.
	  If I am not mistaken, each Haskell compiler and Hugs has
	  its own version of "unlit" program. However, each
	  "unlit" is compiler specific and dependent on other
	  *.c and *.h files. There is nothing platform or compiler
	  specific in this problem that could not be handled
	  by a generic utility, running ouside any Haskell system.

	+ Code and comments extractor
	  A code extractor ("give me a list of default methods for class
	  XXX", etc.) from Haskell sources would be a useful addition to
	  any kind of a high level GUI browser. Its logic could be much
	  simpler if source modules were first prefiltered by "unlit".
 
	From my utilitarian perspective, it does not matter whether
	such utilities are developed in Haskell and then compiled to C
	or in your framework of a pure C - as long as they are generic,
	lightweight and C-compilable on any platform (Unix for
	start).

	I am brewing my own code for such tasks, but I would gladly
	use somebody's expertly designed utilities instead.
