See http://labs.trolltech.com/blogs/2009/01/23/iterating-efficiently/

"Bottom line: If you - like me - value the readability of foreach, you 
should probably get used to writing foreach (const Type &, list) (that is, 
whenever you do not alter the value). Otherwise the different styles of 
iterating do not really differ performance wise. Whatever you do in the loop 
body will in most cases have a much larger impact"
