You can use (as I proposed originally) an external class definition:
(see the external name just after the class keyword)

TExternal = class external name 'anonymous'
    public
      name : String;
      function getName : String;
      procedure log( aMessage : String );
    end;


var
   logger : TExternal; external name 'logger';
