Example text

Despite how hard we try to design the messages, either the order of evaluation causes problems, or syntactic sugar appears, or the pattern simply does not work at all. No matter what we come up with, the result always seems contrived and unnatural. To summarize, using multiple messages is causing too much difficulty. While this may seem obvious and perhaps a bit harsh, the phrasing is key because it hints at a problem looking for a solution3 . 3 Note how stating a requirement makes it so much easier to find the answer!

At the same time, it must allow change at a low cost. Therefore, there is no excuse for laziness nor carelessness. Names should not betray the private nature of implementation details either. For example, a message called singleton tells the senders that they will obtain the unique instance. This causes problems immediately. As long as senders of new receive an instance as advertised, why do they need to know it is a singleton? Since the behavior in both cases is to obtain an instance, why should there be 25 Names are read 100 to 1000 times more often than they are written.

Abbreviations waste more reading time than the writing time they save. 26 CHAPTER 2. COMPLEX CONDITIONS more than one way to invoke it? Why should senders of either new or singleton require any maintenance if the implementation behind instance creation were to change? More deeply, naming a piece of behavior in terms of singleton takes the meaning of the message away from the context of the receiver, and puts it in It may be that new is the context of the sender. This allows the sender to cross the boundary of the not always the right receiver, something that only messages should do.
