thread_spawn

Write Rust functions that spawn threads and implicitly return JoinHandles.

```rust

![feature(plugin, proc_macro)]

extern crate thread_spawn;

use threadspawn::threadspawn;

[thread_spawn]

fn foo(a: u8, b: u8, (c, _): (u8, u8)) -> bool { assert!(a + b + c == 5); 5 - c == b }

fn main() { let mut x = 0; let mut y = 1; let res = foo(x, y, (4, 0)).join(); // explicit join call

match res {
    Ok(res) => println!("result: {:?}", res),
    Err(err) => panic!("Thread panicked: {:?}", err),
}

} ```
