title: Where are keywords defined in Ruby?
body: <p>I was looking at the Ruby documentation, and am wondering if everything is an object then 'keywords' are objects as well, correct?  And if so, where are they defined in ruby?</p>
  
  <p>The following page totally confused me caused it showed the object with all the keywords in it, however this is not the official Object that is used by all classes, is this mixed-in somehow from a different class??</p>
  
  <p><a href="http://ruby-doc.org/docs/keywords/1.9/Object.html" rel="noreferrer">http://ruby-doc.org/docs/keywords/1.9/Object.html</a></p>
  
  <p>I guess there are lots of questions above, the main one is: how do ruby keywords get into ruby?</p>
