title: make-operator returns swindleobject
body: <pre><code>#lang swindle
  (require swindle/misc
           swindle/setf
       )
  
  
  (defclass* jacket ()
    (size :initvalue 40 :accessor sj)
    :printer #t)
  
  (defclass* trousers ()
    (size :initvalue 44 :accessor st)
    :printer #t)
  
  (defclass* suit (jacket trousers)
  </code></pre>
  
  <p>If i compile this code and write (make suit) | (make jacket) | make (trousers) into the interpreter, the return is always <code>#&lt;procedure:swindleobj&gt;</code> but it should be sth like <code>#&lt;jacket size=40&gt;</code>.</p>
  
  <p>Did I miss any requires or what am I doing wrong? </p>
