//! Standard functions. Usually imported with `use gazebo::prelude::*`.
//!
//! Contains:
//!
//! * Extension methods for [`str`](str) and slice/[`Vec`](Vec).
//! * Exports the [`Dupe` trait](Dupe).
//! * Defines derive macros such as [`Dupe_`](Dupe_).
//!
//! The derivation macros appended with underscore are like the normal
//! derivations, but don't require the trait on any argument types.
//! For example, given the type:
//!
//! ```rust
//! # use gazebo::prelude::*;
//! # use std::sync::Arc;
//! #[derive(Clone_)]
//! struct Foo<T>(Arc<T>);
//! ```
//!
//! It is possible to use `derive(Clone)`, but that would require that
//! `T` implements [`Clone`](Clone), which is unnecessary. Using
//! [`Clone_`](Clone_) removes that constraint.
