Yep. I’d give the link but I think HN thinks I’m spamming because I’ve mentioned it too many times before in posts - hence immediate death of any submission, so I’m not mentioning it for a while to see if that tails off.

Bottom line: GPL3 for the compiler, standard library exclusions for derived works, so use it for anything but feed me back improvements to the compiler itself, and you don’t get to redistribute it as your own.
