[M3devel] calling an overridden method

[Mika Nystrom]

Sorry I'm being confusing here.

The code is right but I think your question is a bit confusing.

With your init example I don't think you're talking about an overridden
init method but a shadowed method.  You can't call an overridden method
through the widening trick, but you *can* call a shadowed method like
that.
