Yeah, I am aware of Walter's previous statements on this. I think 
it's ridiculous that he wants his language inferior to virtually 
every one of its modern contemporaries in this aspect based on 
implementation issues. I like D's well-defined 
default-initialization and I think it's great for global storage, 
TLS and class/struct fields, but I think local variables require 
a hybrid approach. It doesn't matter if the implementation isn't 
perfect; it's better than the alternative, which is our current 
abysmal situation.
