I have found the following bug. When one tries to replace a full tree by another tree, using the *empty path* as an adress, this does not work.
sage: lt=LabelledOrderedTrees() sage: toto=lt([lt([lt([],None)],None)],None) sage: titi=lt([lt([],'a')],'a') sage: toto[()] None[None[None[]]] sage: with toto.clone() as tc: ....: tc[()]=titi IndexError: tuple index out of range Florent, what do you think ?
