[ ] Always use minimal representation, e.g. simplify rule = (A (B C)) to rule = A B C ...
[ ] Remove Node::Group as it is not needed when objects are composed via Alternation and Concatenation.
[ ] Think about use cases. Does this make simple syntax transformations more difficult?
[ ] How to ensure correctness?

Make this opt-in via ::simplify()?

Leave that for some later time...
