When creating a dataclass using members of other classes that have overridden their __str__ methods, the __str__ method synthesized by the dataclass ignores the overridden __str__ methods in its component members. Demonstrated in attached file. |

I believe dataclasses uses repr() of the members, not str(). Can you try using specifying __repr__ in Teacup? Just __repr__ = __str__ should work. |
