Excellent, thanks.

Once you've committed this, it seems like there should be potential
for haskell scripts to be used in some of the same situations as e.g.
perl scripts.

Is 'runhaskell' supposed to be a standard handle to a working haskell
interpreter, e.g. possibly runhugs or runnhc? Should people put
'#!/usr/bin/env runhaskell' at the top of scripts?
