Hi, as Antoine pointed out in the corresponding issue (http://bugs.python.org/issue14757#msg160870), measuring/assessing real-world performance of my patch would be interesting. I mentioned that I am not aware of any relevant Python 3 program/application to report numbers for (but guess that the speedups should persist.) Since nobody came up with an answer yet, I figured it would be a good idea to ask everybody on python-dev for suggestions... Regards, --stefan
