I debated myself about which one to use in the example. The dunder aliases were added for completeness, to clarify the relationship to the corresponding special method, and I suppose to make it simpler to dynamically call them. I opted to use the explicit name, even though it's an alias because it seemed to make the example more consistent. Normally I would call operator.add. -- https://mail.python.org/mailman/listinfo/python-list
