I still have this floating around - I personally find the :main
command indispensable now, and curse when I get to a computer without
it (or have to use GHCi, again loosing :main). I will probably post it
as a recommendation to the GHC team as soon as its in hugs.

Any final thoughts on whether it should go in or not, and what its
name should be?

Thanks
