Re: how to interrupt maphash

The easiest method is the lisp return-from form. For example:

(let ((ht (make-hash-table)))
   (setf (gethash :a ht) 1
         (gethash :b ht) 2
         (gethash :c ht) 3
         (gethash :d ht) 4)
   (block stop-mapping
     (maphash
      (lambda (k v)
        (format t "~%~A ~A" k v)
        (when (oddp v)
          (return-from stop-mapping)))
      ht)))
