title: Cost of throwing C++0x exceptions
body: <p>What are the performance implications of throwing exceptions in C++0x? How much is this compiler dependent? This is not the same as asking <a href="https://stackoverflow.com/questions/1897940/in-what-ways-do-c-exceptions-slow-down-code-when-there-are-no-exceptions-thown">what is the cost of entering a <code>try</code> block, even if no exception is thrown</a>.</p>
  
  <p>Should we expect to use exceptions more for general logic handling like in Java?</p>
