So I'd need to see where you are populating "children". I don't see that in
the example here (if it is happening, I assume the constructor of UnionCalendar
is doing it somehow) so that would be why nothing gets put into
calendar_children.
if you inline the classes themselves into the test then you'd have an example
others can reproduce.
