    What is the official word on making instances when a class has

Until this moment, I believed that the specification said that making an
instance of such a class signalled an error.  Certainly the change to
make PCL signal this error was a concious one on my part.

But, now that I think about the class redefinition protocol, I can see
that (even though it is a weird thing to do) it is easy for this to be

I wonder what other implementations do.
