Crate clone_block

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

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);
