I just spent a little while looking at adding witnesses to this, and I think
it's actually a bit tricky because of the way the tree structure is defined.
Also, I realised I'm not very keen on the way that a tree is only ever used with
either 0 or 2 children, where the 2 children are always [FL, RL] - I think
defining a special datatype for this would be best, even aside from the
witnesses issue.

I think the feature also requires a test. For one thing this would make it
easier to refactor to improve the data structure.
