That's why I am confused...
Moreover, the spec says (13.1.2):
NOTE Two or more objects joined to each other are effectively
indistinguishable except that they may have different internal
properties. The only such internal property that may differ in this
specification is [[Scope]].
As I understand, that means, if x and y are joined, then:
x === y returns true, but
x() == y() may return false, because their [[Scope]] may differ.
