I'm not complaining. For my purposes (implementing a similar language 
that competes with Python for speed), I welcome the slower speed of 
Python 3!

(Although competing with CPython is too easy. PyPy is more of a problem. 
With the Jpeg benchmark I mentioned, I can beat PyPy up to 6Mpix, but 
then PyPy starts to get faster. At 80Mpix, PyPy is 60% faster.)
