PEP 267 is very similar to my modest proposal. Apparently, functions are
permanently bound to the module they are defined in, so my call site
caching scheme isn't necessary. I vote for PEP 267.
But what about my suggestion of applying the Dlict concept to classes?
Using the call site caching scheme works for methods that may execute
with instances created by arbitrary multiple inheritance. Keeping only
the slot array with each instance and the symbol table with the class
