Each dataclass is converted to a dict of its fields, as name: value pairs. dataclasses, dicts, lists, and tuples are recursed into. Other objects are copied with copy.deepcopy (). but this doesn't type check; mypy complains that it Expected keyword arguments, {.}, or dict(.) in TypedDict constructor.
