I got a ValueError from applying treetransforms.collapseunary on (B (E (C (a 0) (b 1)) (c 2))), ecpecting (B+E (C (a 0) (b 1)) (c 2)):
treetransforms.collapseunary
(B (E (C (a 0) (b 1)) (c 2)))
(B+E (C (a 0) (b 1)) (c 2))
ValueError: Cannot insert a subtree that already has a parent.
I found, that this occurs, because the parent reference E is not deleted in Es children before they are assigned to the new parent B+E.

B+E
