Hi thanks for the details, I didn't know racket that much before and I went diving into your links and that looks very interesting. I wasn't disparaging the approach at all, sorry if it came across like this. Research is research, anyone willing to spend years of their life digging into such a subject should use the most appropriate tech and follow their intuition. I'm just sad in general about the effort expected of developers (me!) or testers (me!), e.g. to write grammars in 3 or 4 dialects to be able to leverage new cool tools ;-) I know they all have their specificities, I wish there was a way to express them in one place/format. I hope this work allows some time in the future to test language parsers, compilers, interpreters, pretty-printers, so I can finally get some kind of answer to 'how do you test it'.
