title: How fast are lambda functions in GCC
body: <p>Having toyed around a bit with <a href="http://en.wikipedia.org/wiki/C++0x#Lambda_functions_and_expressions" rel="noreferrer">C++0x Lambda Expression</a> in G++, I was wondering as to how well the performance will be in general/specific situations compared to alternative ways without using lambda functions. </p>
  
  <p>Does anybody know a more or less comprehensive discussion of lambda expression performance or situations in which one should avoid them despite more comfort while developing?</p>
