     * Create a list of profiled names from function arguments
     *
     * The method takes an arbitrary number of arguments and tries to parse them as profiled names. Arguments
     * may be strings, arrays or objects.
     *
     * String values are interpreted as names — with one exception: If the first two arguments are both strings,
     * the second one is taken as profile IRI. Optionally following string arguments are taken as names again,
     * assuming to share the same profile:
     *
     *      createFromArguments($name1 [, $profile])
     *      createFromArguments($name1, $profile1, $name2, $profile2 ...)
     *
     * Arrays arguments are expected to have at least one argument which is taken as name. If present, the
     * second argument is used as profile (otherwise an empty profile is assumed):
     *
     *      createFromArguments(array($name [, $profile]))
     *
     * Object values are expected to have a "name" and an optional "profile" property:
     *
     *      createFromArguments((object)array('name' => $name [, 'profile' => $profile]))
     *
     * When an array or object argument is consumed, the profile value will be used for any following string
     * argument. You can "reset" the profile to another value by specifying another array or object value in
     * this case.
     *
     *      createFromArguments(array($name1, $profile1), $name2, $name3 ...)

It seems like $profile defined by parameter $profile on line 104 can also be of type boolean or null; however, Jkphl\Micrometa\Infrastructure\Factory\ProfiledNamesFactory::createProfiledNameFromArray() does only seem to accept string, maybe add an additional type check?
