STINNER Victor added the comment: I wrote PR 25393 to micro-optimize _PyType_GetModuleByDef(). It reduces the overhead from +5.7 ns to +3.4 ns (-2.3 ns). Well, I didn't check in depth if _PyType_GetModuleByDef() is the only change in functools.lru_cache() from Python 3.9 to master. Compare

[issue43835] Dataclasses don't call base class __init__

New submission from Paul Pinterits : It's documented behavior that @dataclass won't generate an __init__ method if the class already defines one. It's also documented that a dataclass may inherit from another dataclass. But what happens if you inherit from a dataclass that implements a custom
