Some question about code

[LC-HX]

there are lots of methods which call the methods of superclass that there exactly isn't this method in the superclass and the names of these two methods are always the same. Is this a special feature for Python?
eg. super(SimpleSynchronizationStrategyMixin,self).set_messenger(messenger)
the superclass of SimpleSynchronizationStrategyMixin is object not containing the method "set_messenger". Exactly the name of method containing this line of code is also "set_messenger"

Yeah, read the section in the docs about mix in classes, it's an unusual pattern in most languages and relies on dynamic method lookup at runtime. Very confusing at first but it affords a great deal of flexibility and code reuse.
