Why do you think I'm advocating Java, because the word Java is contained in my post? I know C++, Python, Common Lisp and Haskell pretty good. I asked serious questions why problems are solved in the way they're solved, which language features are missing to solve it in another way. The current way might work for you, but considering bigger projects and human fallibility, I don't think it will scale that well. Restrictions aren't per se something bad. Considering your own limitations, they can empower you to handle even harder and more complex problems.
