Absolutely agree. However there is a "perfect language" for every programmer to learn, depending on their background and spare bandwidth. For many programmers the jump from their primary language to Haskell or others is too high, not only in terms of complexity but also utility. Several colleagues of mine are picking up new languages right now and a common criteria is they want to build something tangible/useful within a limited time. Having access to the JVM and third party libraries they already know is certainly a plus.
