Note that figure 5-4 is not complete. The caption says "After executing the first instruction, the context stack contains a reference to the corner instance variable.", but in the diagram there is no arrow from the stack to the box labeled
3@4. Moreover, the caption says "contains a reference", but the stack contains3@4, which is not a reference, but an object.I did not change the diagram, but I think it should be reviewed.
