title: Other semantics associated with the register keyword
body: <p>The register keyword is <a href="https://stackoverflow.com/questions/578202/register-keyword-in-c">deprecated and mostly ignored</a>.</p>
  
  <p>But this little part of its <a href="https://msdn.microsoft.com/en-us/library/482s4fy9.aspx" rel="nofollow">documentation on the msdn</a> made me wonder.</p>
  
  <blockquote>
    <p>The compiler does not accept user requests for register variables; [...]  However, <strong>all other semantics associated with the register keyword</strong> are honored.</p>
  </blockquote>
  
  <p>What are those other semantics?</p>
