class SomeClassA extends SomeAbstractClass
{
    private SomeClassB $someClassB;

    public function __construct(private SomeClassC $someClassC, SomeClassD $someClassD, private int $int)
    {
    }
}

class SomeClassB

{
    public function __construct(private SomeClassA $a)
    {
        $b = new SomeClassB;
    }

    public function dependAandC(SomeClassA $a): SomeClassC
    {
    }
}

abstract class SomeAbstractClass implements SomeInterface
{
}
