OK, how much time do you need?
--Guido van Rossum (sent from Android phone)
I would like time to investigate this further, but at the moment I think it will either make attribute lookup poorly defined or slow.
Of the top of my head, the problem as a I see it is basically this:
Currently, type.__getattribute__() is a fixed point in the lookup of attributes.
The proposal means that a fixed point is not reached until the cls parameter of type.__getattribute__() is either object or type,
otherwise type.__getattribute__() and type.__locallookup__ must bounce back and forth.
This will slow down *every* attribute lookup for what is a fairly obscure use case.
Cheers,
Mark.

Let's just accept this PEP. It looks like a nice addition to the metaclass machinery and I don't think we'll get much more useful feedback by waiting._______________________________________________

*Bump*.
It would be nice if this could make into 3.4.
