Syntax error in the PHP code generated from the ASTs of New FuncCall and New MethodCall

[Chance]

I need to convert this AST to PHP code, but I got syntax errors in the generated code.

$node = new New_(new FuncCall(new Name('get_class'), [
    new Arg(new Variable('object')),
]), [
    new Arg(new Variable('a')),
    new Arg(new Variable('b')),
]);
echo (new Standard)->prettyPrint([$node]) . PHP_EOL;
// Expected
// new (get_class($object))($a, $b)
// Actual
// new get_class($object)($a, $b)

$node = new New_(new MethodCall(new Variable('this'), 'className', [
    new Arg(new Variable('a')),
]), [
    new Arg(new Variable('b')),
    new Arg(new Variable('c')),
]);
echo (new Standard)->prettyPrint([$node]) . PHP_EOL;
// Expected
// new ($this->className($a))($b, $c)
// Actual
// new $this->className($a)($b, $c)
