[FLOW3-general] Introduce Method WITH parameters via AOP Advice and Interface

[Torsten Blindert]

I'm referring to this Part: http://flow3.typo3.org/documentation/guide/partiii/aspectorientedprogramming.html#interface-introduction

It says 

/**
         * Around advice, implements the new method "newMethod" of the
         * "NewInterface" interface
         *
         * @param  \TYPO3\FLOW3\AOP\JoinPointInterface $joinPoint The current join point
         * @return void
         * @FLOW3\Around("method(Example\MyPackage\OldClass->newMethod())")
         */
        public function newMethodImplementation(\TYPO3\FLOW3\AOP\JoinPointInterface $joinPoint) {
                        // We call the advice chain, in case any other advice is declared for
                        // this method, but we don't care about the result.
                $someResult = $joinPoint->getAdviceChain()->proceed($joinPoint);

                $a = $joinPoint->getMethodArgument('a');
                $b = $joinPoint->getMethodArgument('b');
                return $a + $b;
        }

Which suggests, that a new method looking something like this is introduced:

public function newMethod($a, $b);

And this I like to achieve too.

To be more concretely, I want to add an protected variable, a getter and a setter to security context. New variable and getter can be easily achieved with AOP, but the setter needs to have a parameter (obviously)... and thats seems to be impossible. Currently I make use of \TYPO3\FLOW3\Reflection\ObjectAccess->setProperty which is not as elegant as using a "real" setter method.
