Agree. In my previous project due to very tight schedule I had to find a better way to generalize the models which ended up using a lot of FP way in addition to OO way. In the project I was using Groovy which I didn't explore its FP potential before. Then recently I began to read Scala(A similar language but might be better) books and take course. I've used Scala but not very much. Because of pressure of the previous project now I understand how useful that abstraction can deal with so many problem beautifully by generalization of common patterns. FP Makes Everybody Think Hard.
