Hi Sam, this thread is about removing caller from WebKit's HTML collections other than document.all.

Gecko doesn't support calling any collections other than document.all. We don't see interop problems. But they could exist. Would you be willing to try removing caller in nightlies and see how that goes? That might start the ball rolling.

Right now we have a circular reasoning (if you can call it reasoning) situation where the HTML spec uses caller for collections that are not callable in Gecko, and when I asked for the spec to remove caller from these collections' IDL, Anne and Hixie suggested that the browsers that *do* support caller should drop it first. I then asked Anne if Opera would -- no answer yet -- and Oliver suggested I try you. I hope with your help, we can end this Mexican stand-off.

My opinion is that the spec should drop caller anyway, since Gecko does not implement it and I know of no content that detects or version-sniffs to use callable collections in non-IE branches of JS control flow. But what do I know?
