Comment #29 on issue 164 by mike.capp: Wrong order in Object properties interation
http://code.google.com/p/v8/issues/detail?id=164
Is it not possible to limit these massive optimizations to cases where the object in question was created via the Array constructor? Or cases where the insertion key was specified as a number rather than a string?
A lot of code out there *is* assuming, however wrongheadedly, that objects will preserve insertion order. I'd be surprised if much code makes that same assumption about arrays.
