es6.js

let echo = (str)=>str

export default echo

incantation.sh

traceur es6.js --out compiled.js --modules=commonjs

The --out option does all the Traceur stuffs. Use the --dir option rather.

@guybedford OH FFS LOL

thx man 😄

Sure! It's badly documented yes, and the API isn't ideal with these kinds of subtle distinctions, but that's because these outputs are still kind of evolving too. It's still open though - we can look at removing the outer defineProperty if you don't like it for example.
