changing how instances are "created"

[newseater]

Hello. I need to be able to control how objects are created. Sometimes
when creating an object, i want to reuse another object instead. I've
searched for factory method implementations and singleton
implementations. They were too much of a hack!

My first attempt of doing this was to play around with the __new__()
method. But i didn't quite succed. Then i came up with making a static
method which can create my instances or re-use other instances.
However, the below code I cannot get to work :(

class Creator
	def createInstance(cls, *args, **kwargs):
		anewinstance = cls.__new__(cls, *args, **kwargs)
		anewinstance.__init__(*args, **kwargs)

		return anewinstance
	createInstance = staticmethod(createInstance)
	
	
can anyone help??
