If they add anything to Python, it should be the ability to do functional-style programming without hassle. Right now it's almost impossible to compose functions in an inline style such as used in functional programming languages. Yes, there's lambda, but it doesn't extend into multiple lines, and applying a function to a bunch of lambdas directly leads to line-width overflow. Even JavaScript has better support for functional-style programming. Perhaps Guido should spend a year writing Haskell :)

There are plenty of very good functional programming languages. If you prefer Haskell to Python, just go ahead and use Haskell. Python has a very specific design philosophy which is a focus of readability and the "preferably only one obvious way of doing it".

It's not easy to "just" switch languages. You also have to consider the ecosystem built around them. For example, I love NumPy and SciPy.

I don't think that is true at all. Python allows you to perform many tricks, with overloading operators etc.

You should probably look into the JVM or .net platforms, where the same libraries are available through multiple languages. For example .net have F# which is a very strong functional language, and the JVM have Scala and Clojure.

Pyhton is not really that kind of language.
