Description Ian 'Hixie' Hickson 2010-11-02 02:01:23 UTC 
I keep getting people ask me if we can make HTMLCollection (and other such interfaces, like NodeList, FileList, etc) into something akin to JS Arrays, with .forEach, etc. Would be nice if WebIDL had a generic solution to this.
Comment 1 Cameron McCormack 2011-06-17 06:25:53 UTC 
Is all that is needed here to make the prototype of HTMLCollection.prototype etc. be Array.prototype?  If so, we could just have an extended attribute [ArrayLike] to require this.
Comment 2 Cameron McCormack 2011-06-20 02:39:25 UTC 
Deferring this.
Comment 3 Arthur Barstow 2011-06-29 16:04:57 UTC 
Cameron - given what you say in Comment #2, should this now be Resolved as "Later"?
Comment 4 Anne 2012-11-29 15:38:42 UTC 
This is [ArrayClass] and NodeList uses it (HTMLCollection cannot because of compatibility; might have to be removed from NodeList too for the same reason...).
