//! Macro expansion snapshot tests.
//!
//! Generated test files live in `tests/expand/{category}/`.
//! Known bugs live in `tests/expand/should-fail/`.
//!
//! To regenerate test inputs: `cargo run -p xtask -- gen-expand`
//! To update snapshots: `MACROTEST=overwrite cargo test -p archmage --test macro_expand`
//!
//! Requires `cargo-expand` (`cargo install cargo-expand`).
