Or maybe just add a proper hygienic macros to ES6 and be done with it?

What Hacker News says
12 sourcesSweetjs is unfortunately dead [0] for like 5 years now.
It also doesn't have any typescript awareness which is required to build this kind of functionality - you want to have static type introspection available in macros so you can generate code based on provided types.

In Ultra-minimal JSON schemas with TypeScript inferenceSlightly off-topic, but I really hope that Typescript and Flow(type) can standardize on a type annotation syntax. There are tons of libraries that have annotations written either inline or provided third-party for one or the other, but the existence of two competing syntaxes fractures the community and tooling possibilities. The capabilities and visions of Flow and Typescript are pretty similar[0][1], so I think there's a real possibility of standardization. It also appears that Flow is, at a minimum, intending to support the automatic conversion of Typescript definitions to Flow[2], which would be a good start.
A convergence in the two standards would also potentially open the door to a typed-ECMAscript official standard, which would allow for improved tooling, greater support in libraries and transformers, and eventual browser adoption.

In LispyScript> That said, can somebody implement hygienic macros in JavaScript.
Although I haven't used it hands-on, http://sweetjs.org/ looks impressive.
For example recently sweet.js apparently implemented some cutting-edge Racket macro developments before Racket officially did. :) https://github.com/mozilla/sweet.js/pull/461
In How necessary are var, let, and const?Actually sweet.js just landed infix macros [1] so you can match on syntax that comes before the macro name. This just happened last week so we haven't updated the docs or made an official release just yet.

In Stop Writing JavaScript Compilers, Make Macros InsteadNot yet, but it's theoretically possibly with all the groundwork that's already been done. See https://github.com/mozilla/sweet.js/issues/12
So I should have said syntax-rules (for now). My bad!
In Faster, Better DOM manipulation with Dommy and ClojureScriptMozilla has been working on this since before Aug 1: https://github.com/mozilla/sweet.js/commit/de15
I don't think they know anything about TypeScript before it was made publicly available, which happened a week ago or so.
