  11  *  String.match( regexp )
  12  *
  13  *  If regexp is not an object of type RegExp, it is replaced with result
  14  *  of the expression new RegExp(regexp). Let string denote the result of
  15  *  converting the this value to a string.  If regexp.global is false,
  16  *  return the result obtained by invoking RegExp.prototype.exec (see
  17  *  section 15.7.5.3) on regexp with string as parameter.
  18  *
  19  *  Otherwise, set the regexp.lastIndex property to 0 and invoke
  20  *  RegExp.prototype.exec repeatedly until there is no match. If there is a
  21  *  match with an empty string (in other words, if the value of
  22  *  regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1.
  23  *  The value returned is an array with the properties 0 through n-1
  24  *  corresponding to the first element of the result of each matching
  25  *  invocation of RegExp.prototype.exec.
  26  *
  27  *  Note that the match function is intentionally generic; it does not
  28  *  require that its this value be a string object.  Therefore, it can be
  29  *  transferred to other kinds of objects for use as a method.
