    These are similar to the Map/Set constructors when called with an array,
    except that they are guaranteed to be side-effect free if called with
    a packed array.
    
    This will be useful in implementing structured clone which, as
    specified in HTML, speaks in terms of the internal [[MapData]]
    and [[SetData]] slots without going through the exposed iteration
    ES semantics.
