That's what I suspected judging from the behaviour I've seen. Is anyone else interested in such work? I don't have much time either, in particular I'm not sufficiently familiar with emacs and Lisp to do something useful quickly. > I would prefer to keep haskell as the source block type if only so that > the blocks are fontified with haskell-mode. However something like an > :engine or :compiler keyword could be used to specify ghc or hugs. Good idea, but specifying ghc is ambiguous: it'll have to be either ghci, runghc/runhaskell, oder hugs, or maybe some other interpreter/compiler someone else would like to use (nhc98, etc., there a quite a few). At least the three options I listed all have incompatibilities in even the simplest use cases, owing to the peculiarities of Haskell as a pure, declarative language. Also, using runghc would require the code block to be tangled first into a temporary file. Is that easily done in babel? András
