Description Anne 2013-10-30 19:07:37 UTC 
Because then it would match ECMAScript's spread operator which recently changed to exclude objects that have a length and indexable properties.
Comment 1 Boris Zbarsky 2013-10-30 20:14:17 UTC 
I think this would be quite reasonable, fwiw.
Comment 2 Boris Zbarsky 2013-11-13 00:33:48 UTC 
Note that if we plan to do this we should do it sooner rather than later before people start depending on the current behavior.  c.f. http://crbug.com/314755 and https://bugzilla.mozilla.org/show_bug.cgi?id=937348 and https://bugs.webkit.org/show_bug.cgi?id=124175

https://github.com/heycam/webidl/commit/1615f240136ae801a8a76ac84ac3fea3fbe68611 made JS -> IDL sequence conversions use @@iterator rather than length and array index properties.
