My proposal was that [ ] (actually RHS and LHS independently) would invoke a method using a well known property name if it was present on the object to the left of the [ ].  If the property was not present (own or inherited) then it would fall back to current behavior.

So Object.prototype customization would cover all cases? Except Proxies, of course -- and host objects.
