Gord's outline exactly matches my understanding and seems
to me to be a very neat and appropriately conservative
specification.  If this were implemented, it would 
become my preferred way to write *all* out-of-body 
subprograms, not just those with templated return types.

My only (very tiny) reservation is about the use of
the "extern" keyword.  (And yes, I know that all this
is different again in C[++]).  In an "extern function"
prototype, the extern prefix means "Here's a promise 
that in due course I will supply the details".  
In "extern class", the prefix means "I'm delivering
on my earlier promise".  

At first I thought it would be a good idea to write 
"class extern" to emphasise that difference but, 
when I see the two options written down, I really 
don't like "class extern" at all.  And I can't see
an alternative way to say it without causing a lot
of other trouble.

So I think I'm happy to live with the small 
irregularity in those two meanings of extern.
