DIP 1018--The Copy Constructor--Formal Review

[Walter Bright]

Your DIP, and nobody else is going to do it, so it falls to me.

BTW, everyone should expect the DIP process to be brutal. It has to be, we're 
long past the stage where we can allow misshapen stuff to get into the language. 
Nobody was very kind with my bottom type DIP :-)

You should read the dismissal of mine and Andrei's "static if" proposal for C++! 
(Ironically, it was later adopted after someone else redid it, after removing 
one of its keystone features.)
