Wonderful quote from the Electric XML documentation:

“First off, Ruby does iterators differently than Java. Java uses a lot of helper classes. Helper classes are exactly the kinds of things that theorists come up with… they look good on paper, but using them is like chewing glass. You find that you spend 50% of your time writing helper classes just to support the other 50% of the code that actually does the job you were trying to solve in the first place. In this case, the Java helper classes are either Enumerations or Iterators. Ruby, on the other hand, uses blocks, which is much more elegant. Rather than:

for (Enumeration e=parent.getChildren(); e.hasMoreElements(); ) { Element child = (Element)e.nextElement(); // Do something with child }

you get:

parent.each_child{ |child| # Do something with child }

Can’t you feel the peace and contentment in this block of code? Ruby is the language Buddha would have programmed in.
