title: How to do attr_accessor_with_default in ruby?
body: <p>Some code that I had that used <code>attr_accessor_with_default</code> in a rails model is now giving me a deprecation warning, telling me to "Use Ruby instead!"</p>
  
  <p>So, thinking that maybe there was a new bit in <code>ruby 1.9.2</code> that made <code>attr_accessor</code> handle defaults, I googled it, but I don't see that.  I did see a bunch of methods to override <code>attr_accessor</code> to handle defaults though.</p>
  
  <p>Is that what they mean when they tell me to "Use Ruby?"  Or am I supposed to write full getters/setters now?  Or is there some new way I can't find?</p>
