As you say, this has always been flaky, inconsistent, underspecified,
and unpredictable, so IMO Guido's free to change this kind of thing as
he sees fit. Builtins like list() or len() which implicitly do
attribute access under the covers should be free to raise either
exception, and good defensive programs have already probably been
catching both.
I know there's no danger in changing the behavior for an explicit
instance.attr access. We all agree that that should always raise
AttributeError, right? :)
