title: Rails cannot find model with same name as Ruby class
body: <p>I'm fairly new to Ruby on Rails, and I have a project with a "Set" model. This is in Rails 2.3.2. Now the problem is that it can't find any methods on that model's class at all. For example: "undefined method <code>find' for Set:Class" or "undefined method</code>errors' for #". It seems to be trying to find those methods on the Ruby "Set" class instead my model class. </p>
  
  <p>It might work if I could write the fully-qualified name of my Set model class like Module::Set, but I'm not sure what that would be. (And yes, I really do want my model name Set. Anything else would be awkward in the context of my app).</p>
  
  <p>Any ideas?</p>
