RE: #! for GHC?

Can GHC be invoked somehow via the #! mechanism? Put another way, is there a GHC analogue to runhugs?

Almost, but not quite. Since 6.2, GHC has the -e switch for invoking expressions from the command line, which gets a step closer. GHC doesn't ignore the '#!' line yet, but I can add that. Then, as far as I'm aware, it should work, albeit a little slowly because it goes through the ordinary GHCi startup which loads some packages etc. Cheers, Simon
