Testing it is really easy, four simple steps:

This script may even simplify testing of large code bases: ------- #! /usr/bin/env runhaskell

After making it executable you can run it as shell script and pass names of Haskell files -- (something like) this will check all Haskell files (literate or not) in your home directory: find ~ -name "*hs" | xargs parse-haskell.lhs Cheers, Sebastian -- Underestimating the novelty of the future is a time-honored tradition.
