Summary

This chapter explored the topic of domain control structures. Domain control structures go way beyond libraries, or even built-in functions and operators, in terms of supporting programmers' abilities to solve problems in new application domains. Most of the time, domain control structures simplify code and reduce the occurrence of bugs in programming that would be prevalent when programmers develop their code using generic mainstream language features.

The next chapter will present the challenging topic of garbage collection. Garbage collection is a major language feature that often distinguishes low-level system programming languages from higher-level application languages and domain-specific languages.
