Not multiple such functions, created anew every time one is implicitly requested.

How is this determined? You get one per object, i don't see how the spec defines a single instance of that function shared everywhere.
That said i am annoyed that the spec require strict mode functions to have this property. It means that in strict mode we have to instantiate this property, rather than simply not having it present.

See 13.2 step 19 and 13.2.3.

This is fixed in ToT, I think by the bug I've duped to.
cheers!, G.
