Does anyone know why CLOS does not provide a copy protocol. Although it is true that in some cases the semantics (as well as the implementation) of what do we mean by making a copy of an instance can be non-trivial, I would argue that the same is true with changing the class of an instance. Nevertheless, CLOS provides a protocol for this, why not for copy... thank you! jose' PS I am looking for reasons why CLOS doesn't include a copy protocol, not necessarily for examples on how to implement one.
