I second that as well. Strong programming skills transfer across languages and the more different languages you know, the stronger programmer you will be in all of them. Also, different programming paradigms are emphasized in different languages (functional, OOP, declarative, imperative are the simplest examples...). Knowing these different languages will expose you to these different paradigms and that's very valuable, I think.
