Introduction

One of the beloved feature of |Ruby is the block based Iterator. A Ruby Iterator is simply a method that somehow loops over the contents of an object. The verb `iterate' means "do the same thing many times' so `iterator' means "one which does the same thing many times'. It can also be considered as an object that behaves like a generic pointer. The iterator usually reference to one particular element in the object collection and then modify itself so that it points to the next element.
