Ans this in turn begs the question, does the author even *know* what
versions her software works on? Not everyone who uses Python is in touch
wiht the hjistory of its syntax and feature set. If I start using Python
tomorrow, do I have to learn what features 1.5.2 includes so I can provide
backward compatibility?
