title: Defining names in place of "true" and "false" for bool type
body: <p>I am wanting to use a <code>bool</code> to switch back and forth between loading X and loading Y from a file. I don't want to use "true" and "false", because it doesn't make the code clear. I would rather use something like LOAD_X or LOAD_Y... Is the following code the way to do it? Or is there a better way?</p>
  
  <pre><code>#define LOAD_X true
  #define LOAD_Y false
  </code></pre>
  
  <p>Edit: Okay, so it seems an <code>enum</code> is the way to go... but what should the naming scheme be? Like all caps, or lower case for the first word, uppercase for following words, etc.</p>
