you could use an introduction to insert an 'operator new()' into Formula.

If the class already has a new operator an execution advice (around 
advice without tjp->proceed()) would do the job.

Note that in the current version of AspectC++ you have to chance to 
check whether the class already has a new operator or not.

I hope this helps,
