Well, that implicit assumption is exactly the one I was questioning;
*is* it OK not to be very concerned about what the behavior is? ISTM
that how the system handles these cases will constrain the use of the
%TYPE feature into certain pathways. The limitations arising from your
original patch presumably don't matter for your intended use, but they
may nonetheless be surprising for people who try to use it differently.
(We've seen cases before where someone does a quick-and-dirty feature
addition that fails to act as other people expect it to.)

I wanted to see a clear understanding of what the corner-case behavior
is, and a consensus that that behavior is acceptable all 'round. If
the quick-and-dirty route will be satisfactory over the long run, fine;
but I don't much want to install a new feature that is immediately going
to draw bug reports/upgrade requests/whatever you want to call 'em.
