I feel a little bit nerd sniped - halfway through the article I wanted to cry out "but the loop!" and then they moved the loop. Nice job, I'm super excited to use this in my own code. I have a bunch of handwritten metadata about C++ classes that I'd rather ditch and use something that the language provides.

If you want, give it a shot with the prebuilt image and let me know if it works for you.

I want to make this project as mature as possible for when support arrives at the upstream version of clang, gcc and msvc. Feedback is appreciated!
