Based on a suggestion, I’m going to build the BowlingGame in yet another way: based on a Stream concept. This will be more fun for me than what I should be doing: I hope it’s the same for you.

A famous author also refreshing his Smalltalk proposes a single method solution. Going where no man dares to tread, I’m going to try to refactor it into the style I consider to be “good”. You decide.

I had this cool idea for another way for Bowling to work. I’m snowed in, so I tried it. The results were good … and very thought-provoking.

Some discussion of style triggered by reader input. Then on to another “improvement”, followed by discussion of whether it’s an improvement, and why we did it.

Let’s try some more incremental improvement to the objects. Meanwhile, some people think I’m taking bites that are too big. Let’s think about that as well.

Let’s reflect a bit on the Smalltalk bowling experiment so far. And then … I’ve got an idea!

In the previous article, we made our first test run, and sketched a bit about how Smalltalk helps us. Let’s make some more tests run.
