Comment (by Frederik):

 That's good to hear... Two comments:

 - Shouldn't runghc/runhaskell be calling the ghc which it was installed
 together with (rather than the one in the path)? I think the path location
 of ghc shouldn't be part of the interface of runhaskell. Also, that would
 make compatibility with older versions of ghc not an issue, if i
 understand correctly.

 - Don't .lhs files have a larger minimum size? I think for this reason we
 should prefer .hs files for scripts as a default, because scripts often
 like to be small...
