## What it is
MacroKata is a set of ordered, hands-on exercises for learning how to write declarative macros (macro_rules!) in Rust. It ships with a small CLI binary that verifies each solution by checking that your code compiles, runs correctly, and expands to the same code as the reference solution.

## Use cases
- learn how to write macros in rust
- practice writing macro_rules declarative macros
- hands-on exercises for rust macros
- understand what my rust macro expands to
- rust macro tutorial with graded tasks
- improve rust metaprogramming skills through kata

## When to choose
- You already know basic Rust and want structured practice writing declarative macros
- You learn best by completing exercises with verifiable, compiler-checked goals
- You want to compare your macro expansion against a reference solution using cargo-expand

## When to avoid
- You want to learn procedural macros - use dtolnay's proc-macro-workshop instead
- You are completely new to Rust and have not finished a beginner tutorial yet
- You need a production macro library or tool rather than learning material
