Thanks Joel! In this case I think it does because I would like to have the same short benchmarking script to be runnable by Python 2 and Python 3. The only piece of code that doesn't run on Python 2 is a to_bytes() single call. So it's not a huge maintenance load. ;) I didn't try to write 'portable' code to Python 3 yet.
