Fix bug handling default values for frozen & slotted dataclasses #569

Closed jcrist closed 11 months ago

jcrist commented 11 months ago

Previously there was a bug where dataclasses or attrs classes with slots=True, frozen=True wouldn't be able to properly use default values for optional fields.

Fixes #567.
