+/// In SHOUTY-KEBAB-CASE, word boundaries are indicated by hyphens and all
+/// words are in uppercase.

+/// ## Example:
+///
+/// ```rust
+/// use heck::ToShoutyKebabCase;
+///
+/// let sentence = "We are going to inherit the earth.";
+/// assert_eq!(sentence.to_shouty_kebab_case(), "WE-ARE-GOING-TO-INHERIT-THE-EARTH");
