Ya know, I hate myself to admit it but I'm liking this idea.  The one
that got me was this:

        foreach my $uid (@users) {
            print it if is_luser($uid);
        }

I like the way it reads.  If 'it' is read-only it limits the potential
complications.  Yes, you can do similar things with grep...

        print grep is_luser($_), @users;

but TMTOWTDI.

I am a bit worried about having to do so much pointer copying to
support this feature.


PS  'it' could take many forms
