I assumed we would keep toDebugString, but use your new pretty printer instead.

Yes, that was the original plan. But then I saw that it is only used in one
test. Do you still think that it would be useful to keep this method?

Yes. We often use the method for debugging by "print".

I see. Got back toDebugString() that returns node tree.
