use std::thread::spawn;
// Test that we give a custom error (E0373) for the case where a
// closure is escaping current frame, and offer a suggested code edit.
// I refrained from including the precise message here, but the
// original text as of the time of this writing is:
//
// closure may outlive the current function, but it borrows `books`,
// which is owned by the current function
fn main() {
let mut books = vec![1,2,3];
spawn(|| books.push(4));
//~^ ERROR E0373
