Since cond* is aiming to produce "simpler" syntax compared to pcase, I
feel that the concise style of pcase may either be avoided or considered
carefully. In particular, I believe that (PRED ...) in conf* is no
less confusing than (pred ...) that pcase provides. IMHO, the recursive
(PRED1 (PRED2 ...) ...) is more confusing compared to what pcase offers.
