There are a couple of minor problems with the update-instance-structure
section in chapter 2.
In the arguments section, the first sentence where it says "When
make-instances-obsolete is invoked..". It probably means something more
like "After make-instances-obsolete is invoked, of after a class has
been redefined, all the instances must be updated. When an instance is
being updated ...".
In the examples section. I believe the defmethod of
update-instance-structure should be at the end of the example. Even
though this code might work interpreted (in some implementations) it
definitely won't compile. This is because setf of position-rho is used
before position-rho is defined.
