title: What to do with size_t vs. std::size_t?
body: <p>Having just read:</p>
  
  <p><a href="https://stackoverflow.com/q/237370/1593077">Does &quot;std::size_t&quot; make sense in C++?</a></p>
  
  <p>I realize using <code>::size_t</code> is not standards-compliant (although supported by my compiler) when you <code>#include &lt;cstddef&gt;</code>. I want to comply with the standard, but I do not want to prepend <code>std::</code> to all of my <code>size_t</code>'s. So, what is the more customary/popular way to handle this:</p>
  
  <ul>
  <li>write <code>using std::size_t;</code>?</li>
  <li>include <code>&lt;stddef.h&gt;</code>?</li>
  <li>just rely on compiler support?</li>
  <li>something else?</li>
  </ul>
