No, the bugs were not related to E4X.
The w3c shut down the DOM working group. ECMA is never going to standardize this odious () for  VB-ism. So if we implement this, it will be because enough bad content exists that people want to work in Firefox and other Mozilla Gecko-based products, *and* that content's authors don't care or are not even around to fix it. I doubt that is the case. /be

Cc'ing Cameron to confirm this resolution. > ECMA is never going to standardize this odious () for  VB-ism. That's still true. > So if we implement this, it will be because > enough bad content exists that people want to work in Firefox and other > Mozilla Gecko-based products, *and* that content's authors don't care > or are not even around to fix it. I doubt that is the case. No evidence of this, so WONTFIX. /be
Yes, callers are deprecated. The keyword was changed to "legacycaller" to emphasise this, and the spec says explicitly Specifications SHOULD NOT use legacy callers unless required to specify the behavior of legacy APIs.
