23//! Some useful and funny macros.
24//!
25//! To be able to use it, import is as follows:
26//!
27//! ```
28//! #[macro_use]
29//! extern crate macro_utils;
30//! # fn main() {}
31//! ```
32//!
33//! # Examples
34//!
35//! ```
36//! # #[macro_use] extern crate macro_utils;
37//! let s = "bateau";
38//!
39//! if_match! {
40//!     s == "voiture" => println!("It rolls!"),
41//!     s == "avion"   => println!("It flies!"),
42//!     s == "pieds"   => println!("It walks!"),
43//!     s == "fusée"   => println!("It goes through space!"),
44//!     s == "bateau"  => println!("It moves on water!"),
45//!     else           => println!("I dont't know how it moves...")
46//! }
47//!
48//! let y = 4;
49//! let x = tern_c! { (y & 1 == 0) ? { "even" } : { "odd" } };
50//! let x = tern_python! { { "it's even" } if (y & 1 == 0) else { "it's odd" } };
51//! let x = tern_haskell! { if (y & 1 == 0) then { "it's even" } else { "it's odd" } };
52//! ```
