I understand that supporting this requires design tradeoffs that the team wants to avoid. However, if this is not done, it's difficult to see how TypeScript can be considered a serious alternative to Babel and Traceur for ES6 support. It will be a long time (2 years?) until most web apps will have as their minimum browser requirement only browsers that support ES6 iterators. I really think the direction presented in issue 3164 needs to be reconsidered."}}
