Warp is written in D, by the guy who created the language. It doesn't seem weird that Andrei would want to talk about that (especially considering the fact that I assume he's very much interested in seeing D in use in more places).
I had the same question about how it compares to clang though. I suppose now that it's open source, someone can do some testing.
