The Importance of Having a Clear Model in a Domain-Specific Language

This chapter emphasizes the importance of a clear model in a Domain-Specific Language (DSL) and discusses how a DSL should allow expression based on the model, independent of syntax. It explores the distinction between the abstract syntax tree and semantic model and their relevance to the domain's concepts and behaviors. The chapter concludes by highlighting the separation between the syntax tree and semantic model as crucial due to their different purposes.
