Another silent failure, much more expensive, is when you try to write to non-writable properties. (And, apart from this, also the related similar problem with constant variables). I would really like to know the reason for this strange problem with non-writable properties, and try to see if there's any way a better solution can be found than this seriously expensive language bug. -- Ingvar von Schoultz _______________________________________________ Es-discuss mailing list Es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
