title: Initializing c++ std::bitset at compile time
body: <p>I'm trying to initialize a <code>std::bitset&lt;256&gt;</code> at compile time with some of its indices, lets say 50-75 and 200-225 set to 1.</p>
  <p>Based on <a href="http://en.cppreference.com/w/cpp/utility/bitset/bitset" rel="nofollow noreferrer">http://en.cppreference.com/w/cpp/utility/bitset/bitset</a>
  It looks like my 2 options are:</p>
  <pre><code>constexpr bitset();
  constexpr bitset( unsigned long long val ); 
  </code></pre>
  <p>Could someone shed light on how I would initialize my bitset considering the second constructor wouldn't work for large indices?</p>
