…ke the original class collectible (pythonGH-136893) An interesting hack, but more localized in scope than pythonGH-135230. This may be a breaking change if people intentionally keep the original class around when using `@dataclass(slots=True)`, and then use `__dict__` or `__weakref__` on the original class.

An interesting hack, but more localized in scope than GH-135230.
This may be a breaking change if people intentionally keep the original class around
when using
@dataclass(slots=True), and then use__dict__or__weakref__on theoriginal class.
