Given the definition of a dataclass, Name:

@dataclass
Class Name:
  user: str

I need to be able to hash an instance of Name to use as a key in a dictionary. As it’s currently defined, and according to my understanding, it’s not possible without the frozen=True attribute, or a given __hash__ function.

Is it possible to provide Name with a hash function after it’s instantiation? However hackish it may be. Changing the definition of Name is not an option. Wrapping Name in another immutable class is not an option.

I have tried __setattr__("frozen", True) and Name(user="").__hash__ = ..., both do not seem to work.
