===
Many languages have a syntax specifically intended for strings with multiple lines. In some of these languages, this syntax is a [[here document]] or "heredoc": A token representing the string is put in the middle of a line of code, but the code continues after the starting token and the string's content doesn't appear until the next line. In other languages, the string's content starts immediately after the starting token and the code continues after the string literal's terminator.
