uopz_set_hook Invalid

[听风]

php version: 7.4.16

code :

<?php
uopz_allow_exit(true);
$result = uopz_set_hook("eval", function () {
   var_dump("111111");
   exit;
});
var_dump(111, $result);
var_dump(eval("echo 'test';"));die;

output:

int(111) bool(true) testNULL

eval isn't a proper function, so I don't think it's possible to set the hook. uopz_set_hook() should return false in that case, though, by checking whether the function exists. That wouldn't work if the function is defined after the hook has been set.
