Bug report
This is very similar to #79721
from dataclasses import dataclass, astuple
from typing import DefaultDict, List
from collections import defaultdict
@dataclass
class C:
mp: DefaultDict[str, List]
dd = defaultdict(list)
dd["x"].append(12)
c = C(mp=dd)
d = astuple(c) # throws "TypeError: first argument must be callable or None"
assert d == ({"x": [12]},)
assert d[0] is not c.mp # make sure defaultdict is copiedBasically applying the same fix for asdict from #32056 to astuple.
