I of course meant something like this ("either" would actually have
been broken with previous code) :


class ConnectiveSpecOperator (SpecOperator):

     if_all_none = True

     def __init__(self, *specs):
         self.specs = specs
         self.args = self.specs
         self.break_spec = None

     def __call__(self, value):
         self.break_spec = None
         for spec in self.specs:
             matchedone = self.matchone(value, spec)
             if matchedone is not None:
                 self.break_spec = spec
                 return matchedone
         return self.if_all_none

class no (ConnectiveSpecOperator):

     def matchone(self, value, spec):
         if match(value, spec):
             return False
         return None

class both (ConnectiveSpecOperator):

     def matchone(self, value, spec):
         if not match(value, spec):
             return False
         return None

class either (ConnectiveSpecOperator):

     if_all_none = False

     def matchone(self, value, spec):
         if match(value, spec):
             return True
         return None
