Re: copy-object

That article is about the ambiguity of words such as
copy, equal, etc.  The copy operation I want is
basically the same operation as copy-structure, but
applied to objects instead of structures.  Since
copy-structure is in the hyperspec, it doesn't make
sense to me to omit copy-object just because of the
concerns in that article.  How do those concerns apply
to objects differently than to structures?  Here is
what happens when I try using copy-structure to copy
an object:

Error: In a call to COPY-STRUCTURE: #<ABC 2060206C> is
not of type STRUCTURE.
  1 (abort) Return to level 0.
  2 Return to top loop level 0.
