Clarify the meaning of #asOop in Squeak.

=============== Diff against Kernel-ar.217 ===============

Item was changed: ----- Method: Object>>asOop (in category 'system primitives') ----- 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 - whatIsAPrimitive."

+ ^self identityHash! - <primitive: 75> - self primitiveFailed!

Item was removed: - ----- Method: SmallInteger>>asOop (in category 'system primitives') ----- - asOop - "Answer an object pointer as an integer, return negative number for SmallInteger" - - ^ self!
