There are other references and books you can read to help you understand Ruby, so this section is going to focus on differences between Ruby and Perl. We provide some tips and warnings for the Perl programmer along the way.
Ruby will lead you to change your focus. You will notice a change in the syntax and organization of your programs. You will use objects to organize your methods. The object model has a cleaner approach, fewer surprises, and a dynamic flexibility you will not find in Perl. Yet there are enough similarities that you should be able to do a number of things in Ruby that look similar to how you do them in Perl.
