Thanks Ihor. I don't actually use Haskell. Earlier this year I
attempted to complete the Org Babel language documents on Worg,
but couldn't get the obligatory "hello world" code block to behave
in Haskell. I'm guessing that ob-haskell.el actually works for
experienced Haskell programmers and was hoping someone had a
solution to the Prelude> problem. I'm not sure when I might get
back to this.
All the best,
Tom
