+  Normal rules apply. The only special methods that are honoured are
+  ``__init__``, ``__del__``, ``__len__``, ``__getitem__``, ``__setitem__``,
+  ``__getslice__``, ``__setslice__``, and ``__iter__``. To handle slicing,
+  ``__getslice__`` and ``__setslice__`` must be used; using ``__getitem__`` and
+   ``__setitem__`` for slicing isn't supported.
 
 This layout makes the number of types to take care about quite limited.
