+
+PEP 557: Data Classes
+---------------------
+
+Adds a new module ``dataclasses``. It provides a class decorator
+``dataclass`` which inspects the class's variable annotations (see
+:pep:`526`) and using them, adds methods such as ``__init__``,
+``__repr__``, and ``__eq__`` to the class. It is similar to
+``typing.NamedTuple``, but also works on classes with mutable
+instances, among other features.
