- I added some options(brace placement, paren) (see [1]).
- I didn't add indent tokens if anonymous classes are used in the ReturnStatement and Assignment nodes.

// no indent tokens
$instance = new class {
    public function test() {
    }
});

// indent tokens are added
$instance = new class {
            public function test() {
            }
        });

- In case of Function/MethodInvocation, perhaps, they should be added if the wrapping option for Method Call is "Always".

// no indent tokens
test(new class {
    public function test() {
    }
},
$a,
$b);

// indent tokens are added
test(new class {
            public function test() {
            }
        },
        $a,
        $b);

- When "0" is set to the Before Class End option(Blank Lines), it may not be available in normal classes (related to the issue 255313).
I fixed it only if anonymous classes are used.

- We cannot format like the following if multiple interfaces are used and the wrapping option is enabled:

// expected
$instance = new class extends Foo implements
    Interface1,
    Interface2
{

};

// actual
$instance = new class extends Foo implements Interface1,
    Interface2
{

};
or
$instance = new class extends Foo implements
Interface1,
    Interface2
{

};

So, it should be fixed.

Thanks.

Tomas, Could you please review it when you can make time?

Thanks.

Will do it ASAP. Thanks a lot, Junichi!

I prefer this case.

This case is totally OK for me.
