First is function return value should be int, second is function arg should
be int.
So full syntax will be like this

function (integer) test(integer $value) { ... }

That means function takes an integer as argument and returns integer value.
If any is violated - Catchable error will be thrown.

That's my understanding of this patch. Some more examples

function (resource) query(string $table, array $where = array(), array
$limit = array()) { ... }

function (array) getData(string $table, array $limit = array(0, 20), array
$where = array()) { /* cals query and generates an array from result */ }

etc.
