From https://bugzilla.mozilla.org/show_bug.cgi?id=688852#c22 > I'm not quite convinced SetArrayElement is the right thing here. Looking at > it, it's not entirely clear *what* its semantics exactly are. The slow-path > is equivalent to [[Put]]; the fast-path is equivalent to > [[DefineOwnProperty]]. And it looks like we have callers that expect each > of those different behaviors, so there's not really a fix for it. We need to visit all of the callers and ensure they are each doing the correct thing in all cases.
