Seconded. Clojure was a real turning point for me but be warned - once you have the veil lifted re OOP you'll not want to work with Java/C# ever again.
Sadly I don't see any chance that I'm going to use it for real job in the future. The market is too narrow for this language. Hard fact that If I don't use it for the job, I cannot reach to its full potential. Guess it should stay as my hobby language for now.
