title: How can I break an infinite loop at runtime?
body: <p>Say that I have:</p>
  
  <pre><code>b = true;
  while(b){}
  </code></pre>
  
  <p>Is there any way to continue on after this point? Like some way to modify the value of b without stopping and re running the program?</p>
  
  <p>I want to do this as a simple method to pause the program for an unspecified amount of time, that changes all the time.</p>
