I presume so, as the figures for how Warp was faster than gnu cpp were comparable to what Andrei and I measured.

Maybe. But there's a sore thumb in that codebase: GC.disable();

And that will do exactly the opposite for its performance claims (with
regards to advertising it).

Not really. It proves that you can absolutely get work done in D without using the GC.

But D has to prove that you can get work done *with* using the GC. So warp really sends the opposite message.

No matter how good the GC is, the word "GC" turns away a lot of programmers with a knee-jerk response. I aimed to show that one can write effective D programs without using the GC.

I think that's pretty wasteful, why won't you just use clang? What's the point of competing with another opensource project (a very good one, that took a lot of men-hour to do a good C/C++ compiler, including the preprocessor). I understand Walter did this in a couple of weeks, clang have been developed for at least 7 years now, is totally understandable that clang outperforms warp, is enough merit for warp to outperform GCC. I mean, if someone wants to have fun, go ahead, but putting community effort on that where there are so many places that are more important to put the effort on seems a bit silly.

Walter taking 2 weeks to do something comparable to what the clang and gcc guys have done over many years, serves as massive advertising for D.

Also, here we now have an entire project written by the man himself. That should serve as required reading for anybody who wants to learn how to code in the latest D.

And it serves as a benchmark for the best C++ coders. They can try to do the same in C++ in two weeks. (I bet by the end of the two weeks the guys are ready to switch languages!)

+1

Agreed.

Maybe, but sober observers will realize that Walter could probably have done something similar in C++. That doesn't negate your point though, that it's a good ad for D.

I made a first pass through. I notice that almost every 'alias' is of the form

  alias existing_name new_name;

I thought that in the latest D the alias syntax was

  alias new_name = existing_name;

Should I be following Walter's lead with respect to alias?

No, use the new syntax.
