A raw string isn’t correctly terminated because the trailing # count doesn’t
match its leading # count.
Erroneous code example:
let dolphins = r##"Dolphins!"#; // error!To terminate a raw string, you have to have the same number of # at the end
as at the beginning. Example:
let dolphins = r#"Dolphins!"#; // One `#` at the beginning, one at the end so
// all good!
