Writing Basic Macros helps Java engineers practice the Clojure design, tooling, and review choices needed to use this topic in production JVM code.
Writing Basic Macros focuses the intermediate track on decisions a Java engineer must make after the first syntax barrier is gone. Read these lessons as engineering checkpoints: what data shape is being moved, which boundary is stateful, and where Clojure should simplify rather than imitate the Java design.
| Checkpoint | Use it to verify |
|---|---|
| Concept fit | You can explain where Writing Macros changes the design compared with an object-oriented Java version. |
| Implementation shape | You can sketch the Clojure namespace, data flow, and JVM boundary before writing code. |
| Review risk | You can name the main failure mode: hidden mutation, unclear dependencies, over-clever macros, weak tests, or operational blind spots. |
