I am guessing this is more about optimizing if(), since you can already get access to either. Right?

For example, you may access this() using something like:

pointcut pc(MyClass mc) : execution(* *(..)) && this(mc) && if(mc.someCondition());

And the aspect instance using something like:
pointcut pc() : execution(* *(..)) && if(MyAspect.aspectOf().someCondition());

Yes, this is about optimizing if()

Now implemented access to aspect instance with the special name 'thisAspectInstance' available in the if clause():

aspect X {
  boolean doit() {
    System.out.println("In instance check method doit()");
    return true;
  }

  before():execution(* m(..))  && if(thisAspectInstance.doit()){
    System.out.println(thisJoinPoint);
  }
}

It only works for singletons right now - I'll address others as use cases come up.

It guards the creation of the tjp object.  It works for subclassing too:

abstract aspect X {
abstract pointcut p();

boolean doit() {
    return true;
  }

  before():p()  && if(thisAspectInstance.doit()){
    System.out.println(thisJoinPoint);
  }
}

aspect Y extends X {

  pointcut p(): execution(* m(..));

}

When doit() runs the instance will be of type Y.
