DIP 1021--Argument Ownership and Function Calls--Community Review Round 1

[Yuxuan Shui]

Ownership/lifetime is definitely a very useful feature for D. 
However, what is purposed by this DIP seems to be very limited. I 
wonder how useful this will actually be in practice. (That been 
said, since we could easily iteratively improve on top of this 
DIP, this is not really a problem).

It would be nice if this DIP could include some real world bugs 
that would have been caught by this form of ownership/lifetime 
analysis.
