Oh well if 12 lines of code that provide an efficient, elegant (if I do say so myself) and generic solution to the problem are worse than a couple of dozen lines that don't work, use cut and paste, parallel arrays and that would require sym refs to access in some sort or scalable fashion.....

The single variable $token is a metastable operator (if you want to nit pick) and performs far more than a simple flag function as it is also the index key to the hash of arrays.

In my world problem->solution == happiness
