I wrote DMD in C++ because I did not have a D compiler. The next version of DMD 
will be in D.

You don't have to accept slower execution with D. If you don't know how to write 
fast code in D, then you don't have to try any harder to do it with D than with 
C++. All the knobs to turn are there.

I infer from that that you aren't using profilers. I've said before and many 
times that if you're not using a profiler, you aren't getting top performance. 
You just aren't. Just like you aren't going to get an efficient airplane shape 
without wind tunnel tests. Too many variables.

BTW, take a look at "streamlined" car designs from the 1930s, where they did not 
do any wind tunnel testing. It was all based on intuition. Compare with car 
designs today, that are all wind tunnel tested. They're very different (and why 
car designs today have a sameness about them).
