+ 	"This method is for compatibility only.
+ 	In Smalltalk, this used to return an integer unique to each object.
+ 	In Squeak, OOPs are internal to the VM.  Accessing an OOP would be useless anyway since it changes when the object is moved during garbage collection."
- 	"Primitive. Answer a SmallInteger whose value is half of the receiver's 
- 	object pointer (interpreting object pointers as 16-bit signed quantities). 
- 	Fail if the receiver is a SmallInteger. Essential. See Object documentation
