`return proceed()' works in all these cases, whether the advised method returns an object, a primitive, or nothing.

Two things:

1. call(* *(..)) means upon the call to **every** method, not a random one.

2. The sample advice is better written as the following.  (Jean
Louis's example would never execute <stuff after> due to the placement
of his return statement.)
Object around(): <my point cut>
{
<stuff before proceed>
Object returnValue = proceed();
<stuff after>
return returnValue;
}
