  let's you capture the return value of a call.

  Wildcards:  *, .., +

  Property-based pointcuts:

     this and target objects, relationship to static

     args
	
     withincode, within, cflow, cflowbelow

     if

     &&, ||, !, short circuiting

  pointcut declarations

     pointcut allcalls(int n) : call(.. *.*(int)) && args(n)
