You must be kidding. Like many others, you seem to think that Scheme is a typical functional language, which it is not. Learn about ML (i.e., SML or CaML), Erlang, Haskell, etc. You can read, e.g., http://en.wikipedia.org/wiki/Closure_%28computer_science%29 The reason why we have the kind of lambdas we have in python (and scheme, and javascript, etc.) is just that it is way easier to implement. That's all I've said. And people have gotten used to it, without ever realizing they are using something completely different from what Church called the "lambda abstraction". Whether the python/... concept of lambda is useful or not is another, subjective question, that I'm not intersted in. If you're pleased with it, go ahead.
