@RReverser how awkward would it be to let acorn accept an array of tokens as input? Tokens to AST instead of code to AST

@codemixers Hmm, tokens in Acorn format? Why?

@RReverser yeah, it would allow very nice @babeljs and sweet.js interop

@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.
