	Just to explain our motivation for having this...

	We have a container that can intermix C++ and
	python wrapped Foo in a way that observes
	python reference counting for python-side
	items, deletion for dynamically allocated
	C++ items, and no deletion of items
	managed elsewhere.  This results in nice
	consistant behaviour across C++ and Python
	code, but means some Python C API creeping
	into our own framework.

	The GetWrapper annotation certainly helps
	minimise what our MethodCode needs
	to deal with, perhaps we're being a bit too
	far on the bleeding edge making our
	framework so python-friendly...

	With thanks,

	Nigel Stewart
