@codemixers @babeljs AFAIR sweet.js uses esprima which has different token format, so you will need to build own interop layer anyway.

@rreverser @codemixers Already done that. https://github.com/babel/babel-eslint/blob/master/acorn-to-esprima.js#L5-39 …

@sebmck @RReverser nice, I think this is really the only limiting factor preventing macros in babel now

@codemixers @rreverser I don't understand why people want macros in the first place. Only reason I haven't really looked into it.

@sebmck @RReverser macros are insanely useful if used judiciously. consider things like debug builds with additional logging etc

@codemixers @rreverser Do you have an example? Not sure how additional syntax makes that any better.

@sebmck @RReverser one is shorthand for fast iteration, here's an ugly example - https://github.com/codemix/fast.js/pull/21 … - emulates `.map` with a for loop

@codemixers @rreverser That's not related to logging?
