I am not sure. I never tested such case. Try to exclude "B" and see
what happens.

If it doesn't work I will have to tweak Py++ to support such case. It
should not be too difficult.

One possible work around is to export class "B", but without any
members and to give it pretty ugly alias, starting with '__'.
