Comments vs. Self-documenting

Recently I had few talks with my co-workers about the "problem" of writing code comments.
There ware arguments like: "When you use Python you don't need to write comments because it is Self-documenting language". But is it really true? Or the "problem" in fact is only inborn human laziness? What is the purpose of comments?

Impromptu extension updated

Recently the jQuery Impromptu developer Trent Richardson released new 4th version of this plugin.

New version add's advanced event handling, more about it at Trent's blog:
http://trentrichardson.com/2012/03/05/impromptu-4-0-is-more-eventful/

But there is still lack of possibility to use enter key inside prompt's form - it is blocked by default.
So I updated my extension which add this functionality and now it is compatible with jQuery Impromptu 4.x versions.
