// returned:
//   str: The matched string
//   start: The matched string’s start
//   end: The matched string’s end
//   groups: The capture groups defined with parentheses
//
// Accepts RE2 syntax (https://code.google.com/p/re2/wiki/Syntax). You can
// enable case-insensitive matching by prefixing the regular expression with
// (?i). See the linked RE2 documentation for more flags.

// Split splits a string into substrings. Splits on whitespace when called with no arguments.

// specifying max_splits.)

// empty string, which instead produces an array of single-character strings.
