Careful, this may involve recursive propagation through helper nodes. The tree isn't always as simple as that. I think an attribute "is_terminator" on Nodes might do the job. It's set to False by default and to True on all nodes you mentioned above, and is inherited by StatListNode if its last node is a terminator (while dropping its remaining child nodes at the same time) and by all helper nodes that contain StatListNodes. This could be done in analyse_types() (or maybe earlier?).
