How to configure named argument with variadics and autowire in YAML?

Hello,

I'm wondering how to configure named argument with variadics parameter and autowire.

Please look at these example classes:

class Bar
{
}

class Foo
{
    public function __construct(PropertyAccessorInterface $propertyAccessor, Bar ...$bars)
    {
        // ...
    }
}

As we can see, class Foo has $bars constructor param as a variadic.
Without autowire i can configure it as presented below:

bar1:
  class: Bar

bar2:
  class: Bar

Foo:
  arguments:
    - '@property_accessor'
    - '@bar1'
    - '@bar2'

Now, i would like to use autowire feature, but i don't know how to configure it.

Below config doesn't work - exception Type error: Argument 2 passed to Foo::__construct() must be an instance of Bar, array given:

Foo:
  autowire: true
  arguments:
    $bars:
      - '@bar1'
      - '@bar2'

Below config works but only last service is injected:

Foo:
  autowire: true
  arguments:
    $bars: '@bar1'
    $bars: '@bar2'

Is there any way to configure it properly?

Thanks.
