Indeed. Also, it is much easier to upgrade a language that is 
statically typed. In my experience the Python 2 to Python 3 
transition was a relatively smooth ride, and it can be made even 
smoother for a statically typed language.

For D specifically, you can just have a version 2 and a version 3 
front end use the same IR/backend and allow both version 2 and 
version 3 code in the the same executable.

(I have implemented "a < b < c" in an experimental extensions of 
the D compiler. It was easy to do, and isn't even a breaking 
change.)
