[Haskell-cafe] Richer (than ascii) notation for haskell source?

You probably still want to write in ASCII, as keyboards have buttons
for each of the letters in the alphabet, so its much easier. However,
you can format your code nicely using lhs2tex - I use it for all my
papers. I have things like:

%subst alpha = "{\alpha}"

Which means I can write: id :: alpha -> alpha

The code is valid Haskell, and looks super-pretty in papers.
