That's not an argument I agree with, as it would invalidate the need for
short closures, null coalesce, constructor property promotion, etc.
Continuing on the previous example:
```php
$service = $container->get(SomeService::class);
assert($service instanceof SomeService);
// could be replaced with
$container->get<SomeService>();
// or in case of multiple instances:
$container->get<SomeService>('the.service.alias');
// perhaps the service is optional
$container->get<?SomeService>();
```
