Hello! At the moment, Array.prototype.push is (afaics) specified so that it leaks property accesses to Array.prototype, as can be seen in V8/Chrome:
> Object.prototype.__defineSetter__('0', function(val){console.log('GOT
> '+val)}); [].push('FOO')
< GOT FOO
< 1
I think that's bad. Luckily, Firefox doesn't implement it in a
spec-compliant way:
> Object.prototype.__defineSetter__('0', function(val){console.log('GOT
> '+val)}); [].push('FOO')
< 1
... and nobody seems to have noticed, so changing the spec shouldn't
break things for anyone. So, would it be possible to specify Firefox'
behavior and deprecate the currently specified one?
