Here, I think, is the primary reason for your email.  You want my Dog $spot
to retain it's optimizational (!) behaviour.  I'm proposing we put a
different meaning in place.  This doesn't mean the optimization goes away;
we can probably still do optimization in many of the cases you cite,
especially if $ME or self() get adopted.

I've tried to clear up the ambiguity that my Dog $spot still has an
optimizational meaning in v2 of the RFC; it doesn't, necessarily.  It means
"$spot is a Dog object, call the constructor and instantiate it as such".  I
would very much like to know how successful I was.
