What is the difference between <code>Fixnum</code> methods <code>.next</code> and <code>.succ</code> in Ruby? It seems it works identically: <pre class="prettyprint"><code> 1.next => 2 1.succ => 2 </code></pre> If there is any difference why there is two method which do the same?

They are equivalent. <code>Fixnum#succ</code> is just an synonym for <code>Fixnum#next</code>. They even share the same block in the reference manual.
