>  Explicitly using return allows the JIT to perform slightly more optimizations. Without a return statement, each function/method is given several local variables on stack to transparently support returning values without the keyword. Keeping these around makes it harder for the JIT to optimize, and can impact the performance of your code. Look through your functions/methods and insert return as needed. It doesn't change the semantics of the code at all, and it can help you get more speed from your application.

I'm fairly sure that this is a false statement. But wanted to get the opinion experts out there. What do you guys think?
