I'm not sure how anything over 100ms could be considered "fast compile" for a toy program... Basically Pascal, or simple c compilers like tcc should be the benchmark imnho.

That's not to say I don't allow for trade-offs.. I gladly trade some milliseconds (or, grudgingly seconds) for features.

Most of the compile time of that particular program is spent parsing HTML templates and converting them to D code. This is all done by D code provided by a library that runs at compile time as part of a template function instantiation in my code. So the compile time is inflated a bit in this case.
