This has come up before.  It may already be in CVS; I don't remember.

The kernel supplies the arguments.  Try it with "#!/usr/bin/env echo".

Only one argument (in this case, "guile") can be included in the #!
line, or else you'll get different behavior on different platforms.
Some would give you a single argument containing 'guile -s $0 "$@"';
some would give you a just "guile"; perhaps there are some that would
give you "guile", "-s", "$0", and '"$@"' as separate arguments.  But
none of them will substitute the appropriate values for $0 and $@,
because this line is interpreted by the kernel, not the shell.
