title: Regarding the global namespace in C++
body: <p>In C++, should we be prepending stuff in the global namespace with <code>::</code>?</p>
  
  <p>For example, when using WinAPI, which is in C, should I do <code>::HANDLE</code> instead of <code>HANDLE</code>, and <code>::LoadLibrary</code> instead of <code>LoadLibrary</code>? What does C++ say about this? Is it generally a good idea, factoring in issues like readability and maintainability?</p>
