This is how I implement it now. I probably should have told also that 
the pointcut and the manipulation of the flag are located in an abstract 
aspect. Thus, the 'user' of the subaspect shouldn't be bothered with 
adding this manually.

I don't think so for my particular need...

Anyway, there are still a number of features in AspectJ I'd like to see 
in AspectC++ also. For one, the ability to give advice to advice, as in 
the adviceexecution() pointcut-function in AspectJ. (or perhaps through 
added functionality of within(...) or cflow(...) (?)).
