Upcoming change to property descriptors

Hi,

 From the Bugzilla [1], Allen:
"(...) in rev 12 [property descriptors] have been enhanced to include a 
reference to the object (if any) they were produced from. This permits 
an descriptor object to pass through the traps behind 
Object.getOwnpropertyDesceriptor and Object.defineOwnProperty without 
loosing any extension attributes"
I'm not sure I fully understand how this would work.
Would it affect current calls?

David
