They are implemented in the D compiler as part of the language 
design (modules, no preprocessor, avoidance of ambiguities), and 
I believe the C++ compiler is faster than most others, although 
the language doesn"t allow many optimizations, due to the 
preprocessor and the numerous syntaxic ambiguities.

I believe that is one of the reasons why DigitalMars C/C++ compiles 
faster than the rest...
