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