It didn't seem to me that there was a convincing outcome from that 
discussion. We need an actual spec!
(I only fix bugs. I don't make language decisions).

In my opinion, the signature of opEquals is a litmus test for the const 
system.
If it's elegant, we've struck gold.
If it isn't, we've still got work to do.
