Comment (by panne):

 I don't agree with the .lhs default, and the argument that non-literate
 standard Haskell scripts can't start with a #! line is invalid: The whole
 point of the #! machinery is that the "real stuff" starts on the next
 line, and runhaskell should be able to figure out what it is (.hs or
 .lhs). Wrapping short scripts in TeX's \begin/\end or forcing users to
 write Bird tracks is a bit silly...

 Furthermore, I agree that the corresponding Haskell implementation should
 be used, and not a random one in the PATH.
