title: Using Enum as Object keys
body: <p>I have an Enum:</p>
  
  <pre><code>   const ingredients = {
        BREAD_BOTTOM: 'BreadBottom',
        BREAD_TOP: 'BreadTop',
        MEAT: 'Meat',
        BACON: 'Bacon',
        CHEESE: 'Cheese',
        SALAD: 'Salad'
     };
  </code></pre>
  
  <p>Now I want to create a list of ingredients using this Enum, something like:</p>
  
  <pre><code>    listOfIngredients: {
        ingredients.BREAD_TOP: 1,
        ingredients.BACON: 1,
        ingredients.CHEESE: 2,
        ingredients.MEAT: 2,
        ingredients.BREAD_BOTTOM: 1,
      }
  </code></pre>
  
  <p>I try some variations such as <code>${ingredients.BREAD_TOP}</code> but I cannot make the list of ingredients have as key the Enum values</p>
