//! A very simple macro that clones a list of variables before calling an expression.
//!
//! Based on this tweet: <https://twitter.com/untitaker/status/1299812136202493953>
//!
//! ## Example
//!
//! ```rust
//! use clone_block::clone;
//! use std::thread;
//!
//! let foo = "foo".to_string();
//!
//! let thread = thread::spawn(
//! clone!(foo; move || {
//! let foobar = format!("{}bar", foo);
//! foobar
//! })
//! );
//!
//! let foobar = thread.join();
//! let foobaz = format!("{}baz", foo);
//! ```
