Description: For frozen dataclasses, attributes are set via object.__setattr__(name, value) in __init__. That won't work if object is a function argument which is entirely possible if object is an attribute name. The same problem is already resolved for self which is replaced by __dataclass_self__ if self is an attribute name. My solution is to store a reference to object in self and use self.__dataclass_object__ (or even __dataclass_self__.__dataclass_object__) if object doesn't work. https://bugs.python.org/issue34213
