Cannot call closure returned by bindTo

[danog]

Closures returned by bindTo cannot be directly called.

Source:

class a {
    public static function init() { var_dump("test"); }
}

(function () {
    static::init();
})->bindTo(null, a::class)();

Result:

[daniil@daniil-arch jav]$ php src/q.php 
string(4) "test"

[daniil@daniil-arch jav]$ jppm start
-> linux
-> app:run 
-> install 

Fatal error: Uncaught ParseError: Syntax error, unexpected 'function' in res://q.php on line 6, position 2
Stack Trace:
#0 {main}
  thrown in res://q.php on line 6

Storing the return value of bindTo in a variable and calling that works just fine

Workaround:

class a {
    public static function init() { var_dump("test"); }
}

((function () {
    static::init();
})->bindTo(null, a::class))();
