If you want to create more memory efficient instances, you need to \ndo it by yourself or use dataslots.with_slots decorator. \n\n## Usage\n#### Simple example\n```python\n@with_slots\n@dataclass\nclass Point2D:\n    x: int\n    y: int\n```\n####  Inheritance\nAs described in docs, in derived class \\_\\_dict__ is created, because base class does not have \\_\\_slots__. \nSlots are created from all defined properties (returned by dataclasses.fields() function).\n```python\n@dataclass\nclass Base:\n    a: int\n\n\n@with_slots\n@dataclass\nclass Derived(Base):\n    c: int\n    d: int\n```\n\n#### Dynamic assignment of new variables\n```python\n@with_slots(add_dict=True)\n@dataclass\nclass Point2D:\n    x: int\n    y: int\n    \npoint = Point2D(10, 20)\npoint.length = math.sqrt(point.x ** 2 + point.y ** 2)\n```\n\n#### Weakref\n```python\n@with_slots(add_weakref=True)\n@dataclass\nclass Point2D:\n    x: int\n    y: int\n    \npoint = Point2D(10, 20)\nr = weakref.ref(point)\n```\n\n#### Read-only class variables\nWith \\_\\_slots__ it's possible to define read-only class variables. When using dataclasses you cannot provide type \nfor attribute or use typing.ClassVar to declare one. \n```python\n@with_slots\n@dataclass\nclass A:\n    x = 5\n    y: ClassVar[set] = set()\n```\n\n## More about \\_\\_slots__\n* https://docs.python.org/3/reference/datamodel.html#slots\n* https://github.com/ericvsmith/dataclasses/issues/28\n\n[dataclasses_issue]: https://github.com/ericvsmith/dataclasses/issues/28",
