Example of Rust making me happy.

test.rs

use core::task::task;
use core::comm::{stream, Port};

enum MyDataType {
    CoolVariant(int),
    CoolerVariant(~str)
}

fn spewer(port: Port<MyDataType>) {
    loop {
        let value = port.try_recv();
        match value {
            None => return,
            Some(value) => io::println(fmt!("%?", value))
        }
    }
}

fn main() {
    let (port, chan) = stream();
    task().linked().spawn_with(port, spewer);
    chan.send(CoolerVariant(~"Hello"));
    chan.send(CoolVariant(42));
}
