I try:

  (def macex-all (e)
    (zap macex e)
    (if acons.e
        (map1 macex-all e)
        e))

  (mac declare (name prop . body)
    (let old (metadata* name) 
       (= (metadata* name) prop)  
       (let exp-body (macex-all body)
            (= (metadata* name) old)
            (cons 'do exp-body))))
and it works. thanks.
