An architecture note on using Haxe compile-time macros as the smallest design for rules that must never be bypassed at runtime — covering trust boundaries, operational checks, and when to replace macros with external generators.
Functions can't delay evaluation of their arguments — macros can. A practical look at Racket's define-syntax-rule, hygiene, and the macro stepper, with worked examples and honest trade-offs.
Nim macros generate getter and setter methods at compile time, eliminating repetitive boilerplate without runtime overhead.
Crystal’s pattern matching lets you replace nested if/else blocks with concise, type‑safe branches. Learn the syntax, see a step‑by‑step example, and weigh performance trade‑offs before adding it to your codebase.
Learn how Racket's syntax/parse library simplifies macro authoring, reduces boilerplate, and improves hygiene with a worked state‑machine example.
