Again we wink at completion reform -- it changes semantics such that ES5-strict is not a subset of ES6 but we believe no code will notice (we could be wrong). We give up on typeof null and removing the global object. The free variable analysis based on global properties still gives early error on typo wins. That makes the subset relation technically false too but let's also wink at it by considering only strict programs that reach runtime under either an ES5 or an ES6 implementation. /be _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
