title: Static functions vs const functions
body: <p>I'm looking at a member function</p>
  <pre><code>int funct(int x) const; 
  </code></pre>
  <p>And I'm wondering if</p>
  <pre><code>static int funct(int x); 
  </code></pre>
  <p>would be better.</p>
  <p>If a member function doesn't use any of the member variables should it be static? Are there any things that would discourage this?</p>
