Design pattern:
- A pattern is a proven solution to a problem in a context.

Q&A
- factory method
- would it be better if we build the node with `input_items` (no popping), and then determine if we need to build children according to some field/property of the node?
- In JsonMixin.to_dict():
- `for key, value in vars(self).items():`
- `if not (callable(value) or key == 'parent')`
- Would there be better way to determine?
