Same here.  What the deal with these "base" objects?

[Tom Sepez, 2013/05/14 18:21:51]

Implementation details.  Not an interface, therefore the Base isn't really
wrappable in some sense.  Same question as before about whether the Wrappable
should come after the base class that is refcounted.  This is opposite the other
one -- I should at least be consistent once we pick a way.
