Clang Successfully Self-Hosts

Doug Gregor of the LLVM project:

We built all of LLVM and Clang with Clang (over 550k lines of C++ code). The resulting binaries passed all of Clang and LLVM’s regression test suites, and the Clang-built Clang could then build all of LLVM and Clang again. The third-stage Clang was also fully-functional, completing the bootstrap.

Is there any other type of project that offers the same potential for recursive satisfaction as a compiler that can compile itself? It’s a singular milestone for LLVM.
