IIRC, Walter stated that he wanted to add it but decided that it 
would be too much of a pain to do in C++ and is waiting for us to 
fully switch to ddmd before tackling that problem. Similarly, 
Daniel Murphy has ideas on how to improve CTFE (which would 
vastly help compilation speeds), but it would be so much easier 
to do in D that he put it off until we switch to ddmd. It would 
surprise me if there are other speed improvements that have been 
put off, simply because they'd be easier to implement in D than 
C++. So, I expect that there's a decent chance that we'll be able 
to better leverage the design of the language to improve its 
compilation speed once we've officially switched the reference 
compiler to D (and we'll probably get there within a release or 
two; the main hold-up is how long it'll take gdc and ldc to catch 
up with 2.067).
