  asOop
+ "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
