python-like dict syntax in rust thanks to macros

dict.rs

use std::collections::HashMap;

macro_rules! dict {
    ( $( $k:expr => $v:expr ),* ) => {{
	let mut m = HashMap::new();
        $(
		m.insert($k, $v);
        )*
        m
    }};
}

fn main() {
	let x = dict!(
		"hello" => "world"
		,"hello2" => "world2"
	);
	for (k, v) in x.iter() {
	    println!("{}: \"{}\"", *k, *v);
	}
	/** output
	hello: "world"
    hello2: "world2"
	**/
}
