The standard module imported by default into all Rust modules

Many programming languages have a 'prelude': a particular subset of the
libraries that come with the language. Every program imports the prelude by
default.

For example, it would be annoying to add `use std::io::println;` to every single
program, and the vast majority of Rust programs will wish to print to standard
output. Therefore, it makes sense to import it into every program.

Rust's prelude has three main parts:

1. io::print and io::println.
2. Core operators, such as `Add`, `Mul`, and `Not`.
3. Various types and traits, such as `Clone`, `Eq`, and `comm::Chan`.
