Re: GHC's CPP and Cabal's unlit

Ok, yes. So how about what I just implemented, that you put two blank lines between the named chunks?

Yes, that would work. You just need some way of separating/continuing comment blocks, whatever it is.

In particular I'd like to know how well it works for Jon Fairbairn who has .lhs code that uses haddock markup and he uses a little pre-processor to convert it.

I have a feeling his preprocessor doesn't cover this case, from a brief inspection. He uses {- -} to delimit comment sections, rather than -- for comment lines. Alistair
