   I don't have a concrete suggestion, but I do think
   _some_ syntactic indication would help, as opposed
   to discerning whether there's only one sexp.  (Not
   that that's hard to do, but it that difference
   doesn't "saute aux yeux".)

Suppose clauses only fall through if the last form is the literal symbol
:fall-through ?  That is wordier and perhaps less elegant, but it would
make cond* more consistent with cond, and make the fall-through behavior
less apt to surprise.  (And apologies if this turns out to be infeasible
due to some other constraint; I've only been half following this
thread.)
