Very, very interesting stuff, thanks.<p>Every couple of years I spend a couple of months with Lisp and then decide that I actually want to use Lisp to generate code in other languages. Recently I&#x27;ve been on a modern C++ kick, and have been really amazed at how Clang and LLVM are being used to do code indexing.<p>So, C++ + CL + LLVM + scientific computing ... wow!
