If there _are_, then at the very least the spec needs to define what sort of IDL array object this is. There are three different kinds...

Given that .item() returns a new object every time, I don't see the use
cases for returning an IDL array object. On the other hand, there are
drawbacks (e.g. it's not an actual JS array, unlike sequence). Are
there any particular reasons this is returning an IDL array object?
