Again, this would encourage people to put such junk in every module
they write, so it would lose its value.
At this point in the thread I am tempted to propose an optimization
moratorium, just to stop the flood of poorly-thought-through
proposals. If you really want to make Python faster, don't waste your
time in this thread. Go contribute to PyPy or Unladen Swallow. Or go
fix the GIL, so we can use multiple cores.
