According to my notes, CSH looks for a colon ':' as the first token
in a script and passes it on to /bin/sh if the colon is seen.  So perhaps

	:
    eval 'exec /bin/perl -S $0 ${1+"$@"}'
       if $running_under_some_shell;

would do the trick.  But the problem here is that PERL hates the colon!
So you could set up a script like this for script execution, but not
feed it to perl unmodified.

Perl being still under modification, perhaps it could be fixed to accept
this.  Or is there a clever perl-ism that would let us put the colon there.
