 // Useful regular expression syntax:

 // +? is a non-greedy (lazy) +.
 // \b matches a word boundary.
 // (?i) turns on case insensitivy for the remainder of the regex.
 // (?-s) turns off "dot matches newline" for the remainder of the regex.
 // (?:regex) denotes non-capturing parentheses group.
