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.
