Crate echo

Macro echo! and echon! print values separated by spaces without the need to specify "{}" format strings, similar to Linux echo and echo -n commands.

To use the macro, you'll need to include the following declarations at the top level of your crate:

#![feature(phase)]
#[phase(plugin)] extern crate echo;

Then you can invoke it as follows:

let a = 0u;
let b = vec![2i, 4, 6];
// 0 [2, 4, 6] true
echo!(a, b, true);
// 0 (without newline)
echon!(a);
