Yes.

The next D2 update will have one such change, which has been planned for 
maybe the past year. All static and global variables will default to 
being thread local (instead of being implicitly shared). Doing this is 
disruptive, but is critical to credibly supporting multithreaded 
programming.

In testing this out, I've uncovered at least a dozen implicit sharing 
bugs in Phobos. I think this change will have a big payoff for 
multithreaded code.
