I haven't provided a "real-world" example, since I expect you Python Einsteins to be able do an A/B test between Python and Perl yourselves (provided you know Perl, of course, which I'm afraid is not always the case). And why would I use any "custom" version of Python, when I don't have to do that with Perl?
