[issue16808] inspect.stack() should return list of named tuples

[Meador Inge]

Meador Inge added the comment:

I suppose asserting the type wouldn't hurt, but I don't consider it that important:

TestGetClosureVars builds the named tuples directly and compares them.  For example:

        expected = inspect.ClosureVars(nonlocal_vars, global_vars,
                                       builtin_vars, unbound_names)
        self.assertEqual(inspect.getclosurevars(f(_arg)), expected)

Doing this for FrameInfo is awkward because we don't have a frame object to construct
the named tuple with.
