+PEP: 280
+Title: Optimizing access to globals
+Version: $Revision$

+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.
+
+    The expectation is that eventually one approach will be picked and
+    implemented; possibly multiple approaches will be prototyped
+    first.

+Montanaro's approach: tracking globals
