title: Symfony 4: bind vs arguments keyword to explicitly inject dependency
body: <p>As far as I am concerned there are two ways (both working properly for me) to explicitly inject a dependency to a service:</p>
  
  <p>a) using the bind keyword</p>
  
  <pre><code>App\Service\ServiceA:
      bind:
          $myService: '@myserviceid'
  </code></pre>
  
  <p>b) using the arguments keyword</p>
  
  <pre><code>App\Service\ServiceA:
      arguments:
          $myService: '@myserviceid'
  </code></pre>
  
  <p>Is there any difference between them? Thank you!</p>
