Nope, different. c[:] holds many behaviors that change dynamically. So c[:]() -- or the more recent go(c)() -- executes all those behaviors. This is very useful for many performers. The real world example that I'm working one is a collaborative visual music performance. So c can contain wrapped MIDI events or sequencer behaviors. c may get passed to a scheduler to execute those events, or c may get passed to a pickler to persist the performance. -- http://mail.python.org/mailman/listinfo/python-list
