Hello, 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? -Iavor On Wed, Jun 19, 2013 at 4:28 PM, Trevor Elliott <[email protected]> wrote: > Hi All, > > I've implemented support for literate markdown in a branch [1].
