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