"with" was already taken by a misfeature of JavaScript, so… I too thought they were introducing something related to the "using" of C++, but the keyword does not seem too bad, in the context of a code, it's very readable. What would you suggest? As for Symbol, it's a JavaScript feature. I bet it was introduced like this so symbols could be polyfilled, so adopted more easily, without making the lack of support a syntax error - i.e. no need to transpile this. A bit verbose, but bearable, and probably easier to parse for a human than a colon. Too much of such terse syntax rapidly makes the code harder to read and more difficult to look up for a novice, or possibly even for someone experimented..
