Much of the runtime has been developing by trying out existing code, then adding support gradually. Of course most of the code I tried out was ECMA3 compliant. I expect to add in support for ECMAScript 5's Object extensions API (defineProperty, getters/setters) as Mug supports them internally, just as Mug already has a global JSON object. The features which could cause incompatibility with existing code is something I'd have to consider separately, so it depends when a majority of authors start writing ECMA5-compliant code (no function.callee, implicit this object bound to global, etc.) |
