Hi,
var o = {};
WeakMap.call(o);
WeakSet.call(o);
Map.call(o);
Set.call(o);
Currently, this works and makes o a weakmap, a weakset, a map and a set...
Sort of. They won't inherit from any of the corresponding prototype types so
none of the relevant methods will be available on those objects. However they
could be explicitly invoked on the object. If you want to make them all
available then the individual methods would have to be installed with
non-conflicting names.
But overall, why should the above be a problem? It is how ES "construction"
works and the way things work for any user defined objects. Why should built-ins be any
different?
hmm... that is... a good argument :-)
