I've got a form field that is either 4, 8 or 12. Naively I'd validate this with Validator::make($data, [..., 'field' => 'required|regex:4|8|12']), but this is syntactically ambiguous and fails.

Neither 'required|regex:(4|8|12)' nor 'required|regex:/4|8|12/' seem to work. I'm not bent on using a regular expression, but I can't find other validators that allow specific options.
