Do not call system-defined functions

Using get_defined_functions, do not call a system-defined function is_callable()

                if (is_callable($state)) {
                    $state = $state();
                }

                foreach ($state as $key => $value) {
                    if (is_callable($value)) { // <----- CHECK IF SYSTEM DEFINED FUNCTION
                        $state[$key] = $value();
                    }
                }

We also need to account for laravel functions (this list is not exhaustive)
