I personally think it should be a Standards Track PEP. This PEP isn't documenting some detail like PEP 13 or some release schedule, but is instead proposing a rather major change to the interpreter which a lot of us will need to understand in order to support the code (and I do realize the entire area of "what requires a PEP and what doesn't" is very hazy). -Brett > > > > > One of the issues in the new project gave formulas for the cost versus > > benefit calculations underlying specialization.
