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