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?
