    #   SO: we can't use tuples as keys in JSON
    #   but the tree uses a lot of tuple keys in Python dicts
    #   so we can map the tuples to UUIDs instead
    #  then we can store the list of nodes mapped to the same UUIDs
    # the goal is to store the tree in a way that makes reproduction possible
