Send arbitrary parameters to functors

In event-handling it would be nice to include custom parameters to pass to the receiving functor.

As an example:

  def listener(event, channel):
    channel.send(event)

  chan1, chan2 = Pipe()
  with Controller as controller:
    controller.authenticate()
    controller.add_event_listener(listener, [CIRC, STREAM], chan1)
    time.sleep(5)

Hi robinson. Wouldn't it be better to use a partial rather than having the Controller track the extra arguments?

import functools

def listener(channel, event):
  channel.send(event)

chan1, chan2 = Pipe()
with Controller as controller:
  controller.authenticate()
  controller.add_event_listener(funtools.partial(listener, chan1), [CIRC, STREAM])
  time.sleep(5)

Replying to atagar:

Yes, it would. I keep forgetting about partial. I'm closing this ticket as not a bug.
