Warp, a fast preprocessor for C and C++

Walter here (author of Warp). AMA about Warp.

Must say facebook has quite the lineup of all-star programmers:<p>- Carmack<p>- Abrash<p>- Alexandrescu<p>- Kent Beck<p>Cannot say I&#x27;m not a little jelly of those who get to spend time with these fine gents.<p><a href="http://www.southparkstudios.com/clips/babjj8/jelly-school" rel="nofollow">http:&#x2F;&#x2F;www.southparkstudios.com&#x2F;clips&#x2F;babjj8&#x2F;jelly-school</a>

Great line from the interview:<p>&gt; WB: I can guarantee that you are wrong about where your code is spending most of its time if you haven&#x27;t run a profiler on it.<p>Definitely a good thing for all programmers to think about!

So, to be clear, this is a reimplementation of cpp?

Are precompiled headers and the performance increase from switching to clang[0] not enough?<p>[0]: <a href="http://clang.llvm.org/features.html#performance" rel="nofollow">http:&#x2F;&#x2F;clang.llvm.org&#x2F;features.html#performance</a>

Could any of this be used to improve comiling speed in other languages?

One thing that really sped up my compiler was eating a ketogenic diet, and eliminating preprocessed foods.

Does Andrei have a sticky D button on his keyboard? He seems to mention it in every other sentence, where as I thought this post was about C and C++.<p>I would ask if there are any improvements between using wrap or just using clang.
