Summary
In this chapter, you've learned that focusing on how the DSL will be used is the key to designing a good DSL. You've seen many examples of DSL usage from a user perspective, and how to implement each of these possible DSLs. Finally, you've learned when it is a good idea to implement a DSL, and when it may not be a good idea. With all you've learned in this chapter, you are better able to decide when a DSL makes sense for your library, and if you decide it does make sense, how better to design and implement it.
In the next chapter, you'll learn all about testing your Ruby code.
