I think Lew has the correct analysis.  I was going more on gut instinct 
rather than analyzing carefully, but I don't see what is better, or more 
clear, or more desirable about your method, compared to the code I posted.

I think it would help if you actually posted your code.  I really can't 
fathom the use case for this, and English prose descriptions aren't 
helping.  I can barely understand what it is you are doing to implement 
this.  The "why" of it is completely beyond me.  Maybe some code will 
spark some kind of idea for improvement....
