My mistake; I see what you're saying. I might not go so far as to say designing and implementing hygienic macros is a /solved/ problem (there's a wide design space) but I do think it's acquired too much mystique. In some ways, what I'm hoping to do with my research is demystify hygiene. > Ingvar's sugar proposal seems free of capture problems, at a glance, Yes, I believe it doesn't have capture problems. > even if sugar definitions nest.
