The most typical use, is a defstruct like macro, which derivates
"public" names from a base name.


   (DEFSTRUCT COLOR RED GREEN BLUE)

generates function definitions for:

   MAKE-COLOR COLOR-P COPY-COLOR COLOR-RED COLOR-GREEN COLOR-BLUE


Ask yourself, what should:

   (DEFSTRUCT other-package:|color| |Red| other-package:|GREEN| |blue|)

generate?

(And the effect *print-case* should or should not have on that...)
