@gaearon ### JS Features These apply to all the existing JS code examples: - Report syntax errors and import-related errors with red squiggles. Other kinds of errors, especially type errors,...

`sed` issue is probably a BSD vs GNU thing

I can move those commands into package.json scripts if you find that more palatable.

One of my eventual goals (per #18) is to publish the compiler to NPM; for that it would be good to provide typings for the AST.
