I would make that the contnrs unit. I think it belongs more together with 
objects such as a stack and queue...

What is the performance difference between a hash() and a binary search on 
an ordered list ? I've also been working with an 'associative' stringlist, but
I was using an ordered stringlist to keep the data, so a binary search is done.
