I often find myself writing meta decorators::

    _reg = {}

    def register(name):

         def meta(func):

              _reg[name] = func

              return func

         return meta

Or some such thing. And that solution is very often enough. But, for the times when you need a bit more control, I've created ``Registrar``. The situation that prompted me to write this was within the confines of a class -- and the functions were being "registered" before they became bound...

Anyway, here's a sample of Registrar in action::

    from registrar import NamedRegistrar

    class Spam:

        def __init__(self):

            self.events = self._events.bind(self)

            # or

            self.shop = Shoppe()

            for event, value in self._events.bind(self):

                self.show.addEventHandler(event, value[0], **value[2])

        ## setup events

        _events = NamedRegistrar()

        @_events('cheese', bubble=False)

        def onCheese(self, baz):

            pass

        

        @_events('eggs')

        def onEggs(self, baz):

            return 'no eggs. cheese.'
