/* You need either an empty +initialize method or an empty -forward:: method. 
   The NeXT runtime unconditionally sends +initialize to classes when they are 
   first used, and unconditionally tries to forward methods that the class 
   doesn't understand (including +initialize). If you have neither +initialize 
   nor -forward::, the runtime complains.  

   The simplest workaround is to add

      + initialize { return self; }

   to every root class @implementation.  */
