Excerpt from stdlib's bool.gleam
================================================================================

//// A type with two possible values, `True` and `False`. Used to indicate whether
//// things are... true or false!
////
//// Often is it clearer and offers more type safety to define a custom type
//// than to use `Bool`. For example, rather than having a `is_teacher: Bool`
//// field consider having a `role: SchoolRole` field where `SchoolRole` is a custom
//// type that can be either `Student` or `Teacher`.

import gleam/order.{Order}

/// Returns the opposite bool value.
///
/// This is the same as the `!` or `not` operators in some other languages.
///
/// ## Examples
///
///    > negate(True)
///    False
///
///    > negate(False)
///    True
///
pub fn negate(bool: Bool) -> Bool {
  case bool {
