///

///
/// ```
/// # use dust_lang::Value;
/// let boolean = Value::boolean(true);
/// let float = Value::float(3.14);
/// let integer = Value::integer(42);
/// let string = Value::string("Hello, world!");
/// ```
///
/// Values can be combined into more complex values:
///
/// ```
/// # use dust_lang::Value;
/// let list = Value::list(vec![
///     Value::integer(1),
///     Value::integer(2),
///     Value::integer(3),
/// ]);
/// ```
///
/// Values have a type, which can be retrieved using the `type` method:
///
/// ```
/// # use std::collections::HashMap;
/// # use dust_lang::*;
/// let value = Value::integer(42);
///
/// assert_eq!(value.r#type(), Type::Integer);
/// ```
