Given that

except (TypeError, AttributeError):

is the "safest across releases" idiom (as suggested by Tim Peters),

would it make sense to make AttributeError a subclass of TypeError so that

except (TypeError):

would become equally "safe" (and simpler)?

Potentially, some exception handling code would behave differently
(break?), but apparently this is already the case given that what is raised
(AttributeError or TypeError) changes between releases.
