These two aren't equivalent, the first example requires the shapename keyword arg, raising a KeyError when it wasn't specified

  That's true. The second one might be better written as: def __init__(self, shapename, **kwds): Or, in Python 3: def __init__(self, *, shapename, **kwds): (making shapename a required keyword-only argument)

    def __init__(self, shapename, **kwds): is not better written; it allows shapename to be passed positionally which makes cooperative inheritance fragile.

      The version that I was rewriting: def __init__(self, shapename=None, **kwds): also allows that.
