On this publication from 2010 http://www.drdobbs.com/blogs/cpp/228701711 you gave some insight and promised a follow up on what design decisions are important to make a compiler fast. Did you happen to have written it?

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...
