Review of DIP53

[Andrei Alexandrescu]

http://wiki.dlang.org/DIP53

There are quite a few similarities with DIP49 so I won't discuss the 
shared parts. In fact my only comment is that I'm unclear on the 
motivation and the progress marked by this DIP (i.e. assuming it's 
implemented to perfection, it would make D better because...). One 
argument is that "current definition is very complex and hard to 
understand" but DIP53 doesn't seem to make matters any simpler.

What adds to the confusion is that some rules already work today so it's 
unclear what's already there and where the changes are.

Overall, I'm not clear what DIP53 does. It may only be a matter of the 
writeup itself. Also I'll note that there might be subtleties of current 
constructors I'm inadvertently glossing over.
