Prelude

You might be wondering how we have access to Vec or Box everywhere without a use to import them. It is because of the module prelude in the standard library.

Know that in the Rust standard library anything that is exported in std::prelude::* is automatically available to every part of Rust. That is the case for Vec and Box but others as well (Option, Copy, etc.).
