All the use cases seem to be about adding some kind of getattr hook

anyway. So why not tackle that problem head-on and modify module_getattro()
to look for a global named __getattr__ and if it exists, call that instead
of raising AttributeError?
Not sure if anyone thought of it. :) Seems like a reasonable solution to me.
Be curious to know what the benchmark suite said the impact was.
Why would there be any impact? The __getattr__ hook would be similar to the
one on classes -- it's only invoked at the point where otherwise AttributeError
would be raised.
I think the bigger question is how do we support it back on 2.7?
I do not understand this question. We don't add new features to 2.7 and
this definitely is one.
