   It could have been built into each object in the other 'direction' also, I   
   mean having each instance contain a 'versioned_class' pointer, and then each   
   'versioned_class' having its 'version+class' information, you would win one   
   int per instance and one class_desc.version_array[version] indirection.   
      
   just my 2 cents
