    I don't think this captures the spirit of the original question.  If you do 
this,
you rely on the evaluator checking for the existence of the binding - procedure?
gets the actual object (it never sees the name).  Or, if the name hasn't been
bound it will error out (if the lookup throws an exception, that might be used).
