Oops, Skip's and Jeremy's approach already have their own PEP. 

Reference those instead of trying to incorporate them.

Abstract
This PEP attempts to summarize various approaches for avoiding the
dictionary lookup for accessing globals and built-ins in most
cases. There are several competing approaches, which originated
in historical order by authors Montanaro, Hylton, and Van Rossum.
The fourth author is added for his valuable feedback during all
stages.
This PEP describes yet another approach to optimizing access to
module globals, providing an alternative to PEP 266 (Optimizing
Global Variable/Attribute Access by Skip Montanaro) and PEP 267
(Optimized Access to Module Namespaces by Jeremy Hylton).
The expectation is that eventually one approach will be picked and
implemented; possibly multiple approaches will be prototyped
first.
