title: Can heroku config vars be boolean and can ejs access it?
body: <p>Can I set <code>process.env.production</code> to <code>true</code> or will it be converted to <code>"true"</code>?</p>
  
  <p>I.e. Must config vars in Heroku always be strings, or can they be boolean?</p>
  
  <p>Also: If an <code>if/else</code> condition in my <code>index.ejs</code> executes on <code>process.env.production</code> being set to <code>true</code>, will it be evaluated before being rendered?</p>
