[ .... ] One thing I noticed was that the implementation makes no use of macros, except for a trivial macro which "renames" cond* itself. This is in contrase to pcase.el, which uses macros extensively, requiring lisp/emacs-lisp/macroexp.el to work. In its turn macroexp.el uses pcase. This leads to an unlovely artifice at bootstrap time. The macro in cond* can be expanded by Fmacroexpand in src/eval.c. Thus, at bootstrap, condstar.el could simply be loaded before macroexpand.el. This is a Good Thing, and I'm sure it's not an accident. Please keep this feature as cond* get amended and further developed. > -- > Dr Richard Stallman (https://stallman.org) > Chief GNUisance of the GNU Project (https://gnu.org) > Founder, Free Software Foundation (https://fsf.org) > Internet Hall-of-Famer (https://internethalloffame.org) -- Alan Mackenzie (Nuremberg, Germany).
