                  Learn how messaging makes your object-oriented code easier to read and maintain.
                  Have you ever heard, objects are communicating by messages? I had heard this a
                  long time ago - and never have been able to make sense of it. But why bother?
                  Just calling functions on objects gets the job done, doesn't it. That's how I
                  programmed until a couple of years ago, at least. However my dismay was growing
                  every day. I found it hard to derive classes/objects from requirements. And
                  despite all my best OO-intentions peppered with Clean Code principles my code
                  was hard to read.
                  So I started to think about whether this was all my fault, and how to try harder
                  to become a good OO-programmer. But then I realized: This wasn't just my
                  problem. Almost every developer I met suffered from the same symptoms. So maybe
                  the true cause of this wasn't our collective dumbness. Maybe the true cause lay
                  in the paradigm.
                  And that's what I'm believing today. Mainstream object-orientation is more of a
                  problem than a solution, because it's lacking an essential, no, the essential
                  aspect of object-orientation how its inventor Alan Kay meant it to be. This
                  essential aspect is messaging. Yes, the way of how objects are communicating
                  makes a big difference. And glossing this over by just saying "it's like calling
                  a function" has done great harm.
                  In this little book I´m trying to show you what I think, messaging means and
                  how object-orientation was intended to be.
                  I'd be happy if you gave messaging a second chance. I'm sure you'll reap
                  benefits from putting it back into the center of your object-oriented
                  programming practice. Your code will become easier to write, read, and change,
                  since it will more closely resemble the requirements and your solution strategy.},
