def mro(self, cls):
ups = inspect.getmro(cls.cls)<EOL>return list(map(lambda c: self.find_class(c), ups))<EOL>
Returns a method resolution list of documentation objects
for `cls`, which must be a documentation object.

The list will contain objects belonging to `pydoc.Class` or
`pydoc.External`. Objects belonging to the former are exported
classes either in this module or in one of its sub-modules.
