To Álvaro: We’ve just had a conference–Andrei, Walter and I. We decided 
that we have a deadline for D2, so we have to cut some features and 
postpone them to D3. The race-free type system won’t make it–there just 
isn’t enough time to implement and test it. There will be however a 
stopgap solution for message passing in Phobos. It will be limited but safe.

See comment 15.

Perhaps Walter, would like to publish or confirm what is on the final 
list for D2. It would reduce confusion and rumour.
