-+ simple mixins somewhat work too, but the mixed in class needs a
-  ``_mixin_ = True`` class attribute. isinstance checks against the
-  mixin type will fail when translated.

+  body to copy the whole content of a class `M`.  This can be used
+  to implement mixins: functions and staticmethods are duplicated
+  (the other class attributes are just copied unmodified).
 + classes are first-class objects too
