I think that good support for writing literate Haskell in markdown notation
would be great! Over the weekend I updated the wiki page with a fairly
detailed description of the proposal, which Trevor implemented.
What do folks think about the feature, and if we are happy with the design,
would there be objections if I merged it in?
