title: Merging objects with twig overwrite results rather than adding them together
body: <p>How can I combine these to objects:</p>
  
  <pre><code>{% set stuff1 = {
    array: [
      {
        one: 'A',
        two: 'B'
      }
    ]
  }
  %}
  
  {% set stuff2 = {
    array: [
      {
        one: 'C',
        two: 'D'
      }
    ]
  }
  %}
  </code></pre>
  
  <p>So that this is the result?:</p>
  
  <pre><code>{% set result = {
    array: [
      {
        one: 'A',
        two: 'B'
      },
      {
        one: 'C',
        two: 'D'
      }
    ]
  }
  %}
  </code></pre>
  
  <p>Ive tried this, but it overwrites the first array rather than adding to it: </p>
  
  <pre><code>{% set result = stuff1|merge(stuff2) %}
  </code></pre>
