//! Utility macros and hint functions.

#![doc = crate::doc_!(extends: hint)]
//
// # Implementation notes
// Several macros are defined hidden, prefixed with `_`, an publicly re-exported
// unprefixed. This fixes able to import them from the root.
// See: <https://github.com/rust-lang/rust/pull/52234#issuecomment-976702997>
// E.g.: bitfield, capture_last, CONST, enumset.
