you'd think with dmd's module system achieving compiler-level parallelism wouldn't be so difficult.
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).
