To me, this sentence clearly implies that the code that follows is the
code that had the problem. Since the posted code cannot run, it clearly
is not. People

Your list probably contains several references to the same object,

The Problem (very basic, but strange):
I have a list holding a population of objects, each object has 5 vars

Which are probably not necessary:
