Exactly. 

  (defmacro foo (stmt . bar) `(list ,stmt ,@bar))

I hope that "ancient-style" doesn't mean anything pejorative.

If you're in the Scheme language this is the behavior I expect.  If you
are in CL the right thing is to support the complete Macro Lambda Lists,
but I wouldn't expect that to work as the Kawa CL implementation is very
incomplete.

Please note the difference in the documentation between

        defmacro name lambda-list form ...
and
        LAMBDA-EXPRESSION ::= (lambda FORMALS [RTYPE] BODY)

one is for defmacro, the other for Scheme lambda forms.
