Thanks :-)

Yeah, that's fine. I was trying to keep inline with RFC 218, because I
thought it would be weird for this:

   my Pet $spot;    # tied
   my Dog $x;       # not
   print "ok" unless (defined $spot or defined $x);

to return true and not print "ok". But I guess you can easily check with
tied() too, and it makes more sense to just tie it on declaration (my
original inclination).

Excellent!

Yes, I believe Piers brought something like that up too, I'll go answer
his thread as well...
