.. _whatsnew37-pep557:
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.
