Because B is NOT declared in the global namespace, and you are not
otherwise specifying a namespace for python to look in, so it checks
local, then global (roughly).  You declared B in the namespace of the A
class.

I tried:

from __future__ import nested_scopes

but that doesn't work it seems...

Oh well, change one line and it will work:

		self.element = A.B()
