Yeh, a bit too esoteric for most of us to review.  For instance, it is 
not obvious to me, not familiar with internal details, after reading the 
intro, why a custom __getattribute__ is not enough and why 
__getdescriptor__ would be needed. If Guido does not want to review 
this, you need to find a PEP BDFL for this.

There are two fairly obvious non-esoteric questions:

1. How does this impact speed (updated section needed)?

2. Is this useful, that you can think of, for anything other than 
connecting to Objective C?
