- when printing a shared node for the second time, don't print its children (This keeps output proportional to the size of the structure)
- when printing a shared node for the second time, print its type only, not rule (for consistency with above: don't dump details of nodes twice)
- don't abbreviate shared nodes, to ensure we can prune the tree there
