     17 *  String.match( regexp )
     18 *
     19 *  If regexp is not an object of type RegExp, it is replaced with result
     20 *  of the expression new RegExp(regexp). Let string denote the result of
     21 *  converting the this value to a string.  If regexp.global is false,
     22 *  return the result obtained by invoking RegExp.prototype.exec (see
     23 *  section 15.7.5.3) on regexp with string as parameter.
     24 *
     25 *  Otherwise, set the regexp.lastIndex property to 0 and invoke
     26 *  RegExp.prototype.exec repeatedly until there is no match. If there is a
     27 *  match with an empty string (in other words, if the value of
     28 *  regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1.
     29 *  The value returned is an array with the properties 0 through n-1
     30 *  corresponding to the first element of the result of each matching
     31 *  invocation of RegExp.prototype.exec.
     32 *
     33 *  Note that the match function is intentionally generic; it does not
     34 *  require that its this value be a string object.  Therefore, it can be
     35 *  transferred to other kinds of objects for use as a method.
