No, I want a boolean false value.

I already stated that this won't work, it returns __FLOOR_DATE, which  
makes it useless for boolean operations:

     def effective( self ):
         """ Dublin Core Date element - date resource becomes effective.
         """
         marker = []
         date = getattr( self, 'effective_date', marker )
         if date is marker:
             date = getattr( self, 'creation_date', None )
         return date is None and self.__FLOOR_DATE or date

I'd like this one to return False, not some floor value. I understand that  
the official CamelCase accessors always return strings (which is fine),  
but I don't see why "effective()" can't give a False value. Is this just  
historical, or is there a real reason for it?
