It's the same as the part before except this time we save the
continuation and quit in the :before method, and then resume
the continuation on a separate line.  The point of the patch is
to make sure that the logic that runs the various methods of a
generic function occurs in the cc-interpreter, so call/cc can be 
used in any of the methods.
