[issue44674] dataclasses should allow frozendict default value

[Gianni Mariani]

Gianni Mariani <gianni at mariani.ws> added the comment:

@Arjun - this is about default values (See the bug description - Using a frozendict as a default value)

Try this:

from frozendict import frozendict
from dataclasses import dataclass

@dataclass
class A:
    a: frozendict = frozendict(a=1)

This used to work until frozendict became a subclass of dict.

Perhaps another fix is to convert any dict to a frozendict? Maybe not.

How would you handle this case? The only thing I figured was:
from frozendict import frozendict, field
from dataclasses import dataclass

AD=frozendict(a=1)
@dataclass
class A:
    a: frozendict = field(default_factory=lambda:AD)

Which imho is cumbersome.
