You're right about that btw; if an object implements an interface that 
supports indexed properties, then its [[GetOwnProperty]] internal method 
will never look at the prototype for array index properties, and you can 
also not create own array index properties on the object.  So I believe 
the optimisation that Glenn mentions is possible.  But I think the right 
thing here might be to make the changes to distinguishability to make 
this overloading valid.
