DIP 1018--The Copy Constructor--Formal Review

[Mike Parker]

Walter and Andrei have requested the Final Review round be 
dropped for DIP 1018, "The Copy Constructor", and have given it 
their formal approval. They consider copy constructors a critical 
feature for the language.

Walter provided feedback on Razvan's implementation. When it 
reached a state with which he was satisfied, he gave the green 
light for acceptance.
