Ruby makes it easy to implement domain-specific languages (DSLs), and many popular libraries offer DSLs to improve their usability.
In this chapter, you'll learn how to design and implement a DSL, which problems are handled well by DSLs, and both the advantages and disadvantages of using DSLs in your libraries.
