//! Aliases for the type operators used in this crate.

//! Their purpose is to increase the ergonomics of performing operations on the types defined
//! here. For even more ergonomics, consider using the `op!` macro instead.
//!
//! For example, type `X` and type `Y` are the same here:
//!
//! ```rust
//! # #[macro_use] extern crate typenum;
//! use std::ops::Mul;
//! use typenum::{Prod, P5, P7};
//!
//! type X = <P7 as Mul<P5>>::Output;
//! type Y = Prod<P7, P5>;
//!
//! assert_type_eq!(X, Y);
//! ```

// Aliases!!!
