But it seems like a perfectly good and useful feature
in its own right to me. Why force every sequence to
implement its own __iter__ if there is a default one
that does the same as what your custom one would have
done anyway?

An alternative would be to give object an __iter__
method containing the default implementation. But
then you've lost all ability to test for potential
iterability, since everything has an __iter__ whether
it works or not.

So +1 from me on keeping the status quo wrt __iter__
in Py3k.
