yes I figured out that the try always excepted as Klass isn't visible in
2.0.

My best guess for what I want is

class WKlass(Klass):
    def __getattr__(self,name):
        try:
            return self.__class__.__bases__[0].__getattr__(self,name)
        except:
            return getattr(self._parent,name)

ie I figure it safer to assume that the way to get to an instance's
__bases__ is via its __class__ as the name WKlass will get re-used.

The real intention here is to create a class that wraps an existing
__getattr__ if that's present. If that fails or is absent use the
attribute from the _parent (ie the default attribute holder). I think of
it as chaining the __getattr__ methods.
