Re: [pro] Generated symbols

I need comprehensive review of use of generated symbols (make-symbol, copy-symbol, gensym... ) in CL. The books I have (both Grahams, Siebel, barely mention these operators, except for use of gensym in macros.

What are other typical or interesting uses of these?

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...)
