A safe, conservative policy is never to export two overloadings with the same number of parameters. If a method uses varargs, a conservative policy is not to overload it at all, except as described in Item 53. If you adhere to these restrictions, programmers will never be in doubt as to which overloading applies to any set of actual parameters. These restrictions are not terribly onerous because you can always give methods different names instead of overloading them.
