a) a "business" case of throwing anything other than AttributeError from __getattr__ and friends is almost certainly a bug waiting to happen, and

FYI, best practice for __getattr__ is generally to bail with an AttributeError as soon as you see double underscores in the name, unless you intend to support special attributes.

Unless you're in an old-style class, you shouldn't get an double underscore methods in __getattr__ (or __getattribute__). If you do, it's a bug.

Uh, did you see the message that was in response to?

Maybe it should be a bug report?

Old version of Python I think.

If by "old" you mean 2.6, sure. (Also, I did say this was a best practice since 2.2.)
