Biggest Issue with D - Definition and Versioning

[Zachary Lund]

D1 or D2 both don't have a very accurate definition. C and C++ has 
several hundred pages of specifications and while I'm hopefully not 
expecting that, I do want some certainty on what is *supposed* to happen.

There is also no versioning. D2 is definitely different from D1 in the 
case that it's not backwards compatible, but version for the actual 
example implementation isn't enough, especially when that implementation 
doesn't always do what it's supposed to do.
