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. 369273 2 jwalden+bwo 2011-03-17 13:54:54 -0700 See 13.2 step 19 and 13.2.3. 588055 3 barraclough 2012-03-26 13:20:06 -0700 This is fixed in ToT, I think by the bug I've duped to. cheers!, G. *** This bug has been marked as a duplicate of bug 63398 ***
