tor is applied to a method, the type checker will
validate that it overrides a method or attribute with the same name on a
base class.  This helps prevent bugs that may occur when a base class is
changed without an equivalent change to a child class.

There is no runtime checking of this property. The decorator attempts to
set the ``__override__`` attribute to ``True`` on the decorated object to
allow runtime introspection.

See PEP 698 for details.
