title: If I have a hash in Ruby on Rails, is there a way to make it indifferent access?
body: <p>If I already have a hash, can I make it so that </p>
  
  <pre><code>h[:foo]
  h['foo']
  </code></pre>
  
  <p>are the same?  (is this called indifferent access?)</p>
  
  <p>The details:  I loaded this hash using the following in <code>initializers</code> but probably shouldn't make a difference:</p>
  
  <pre><code>SETTINGS = YAML.load_file("#{RAILS_ROOT}/config/settings.yml")
  </code></pre>
