Python vs Ruby holy war thread

Last week I learned Python. It's not perfect but it's pretty damn cool.
This week I'm starting on Ruby. I've just encountered blocks and I would approve if someone would answer this: are blocks merely an ugly kludge because the author did not know about lambda expressions, or can they do something lambdas can't?

They could make a special option, --with-real-integers, which would wrap all basic types so you can subclass them, at the cost of 15% slower programs. I personally wouldn't use it.
