DIP 1018--The Copy Constructor--Community Review Round 1

[Mike Parker]

This is the feedback thread for the first round of Community 
Review for DIP 1018, "The Copy Constructor":

https://github.com/dlang/DIPs/blob/07da1f2cabc8b1bc3ad66034598a133e5ad13356/DIPs/DIP1018.md

All review-related feedback on and discussion of the DIP should 
occur in this thread. The review period will end at 11:59 PM ET 
on January 4, or when I make a post declaring it complete. (This 
time I'm extending the review period by a few days because of the 
holidays.)

At the end of Round 1, if further review is deemed necessary, the 
DIP will be scheduled for another round of community review. 
Otherwise, it will be queued for the Final Review and Formal 
Assessment by the language maintainers.

Please familiarize yourself with the documentation for the 
Community Review before participating.
