title: Is it "iterate through" or "iterate over" something?
body: <p>Just thought about it. Is there a semantic distinction, or are we free to choose?</p>
  
  <p><strong>EDIT</strong> I accepted <a href="https://stackoverflow.com/questions/2715388/is-it-iterate-through-or-iterate-over-something/2715452#2715452">@roygbivs answer</a>, because most of the answers suggested that it is a matter of taste which one to choose, and that it doesn't really change the meaning. In that case, since the <em>through</em> and the <em>over</em> don't carry any information at all (in that particular context), they can be left out.</p>
