WORKS:
{{ product.metafields.test.testmeta.value.first_name.value }}
{{ product.metafields.test.testmeta.value.system.handle }}

{{ collections[collection.metafields.test.test].title }}
{{ collections[collection.metafields.test.test].value.title }}

{{ product.metafields.test.testmeta.value.metafields.test.first_name }}

<section>
  <h2>Collection Only</h2>
  <p>Product only gets a collection...</p>

  <div>
    <strong>PRODUCT PAGE REFERENCING AUTHOR</strong>
    {{ product.metafields.godine.author_collection.value.title }} (LIQUID-ONLY)
    {{ product.metafields.godine.author_collection.value.metafields.godine.title }} (LIQUID-ONLY)
    {{ product.metafields.godine.author_collection.value.metafields.godine.first_name }} (LIQUID-ONLY)
  </div>

  Limitations: - Liquid-only on product page - Lots of collections...
</section>

<section>
  <h2>Product and Metaobject both Reference Eachother</h2>

  <div>
    <strong>PRODUCT PAGE REFERENCING AUTHOR</strong>
    {{ product.metafields.godine.author.value.first_name.value }} (WORKS IN TEXT)

    OR

    {{ collections[product.metafields.godine.author].metafields.godine.first_name }} (LIQUID-ONLY)
  </div>

  <div>
    <strong>AUTHOR (METAOBJECT PAGE) REFERENCING PRODUCTS</strong>
    {% for myprod in metaobject.products.value %}
      {{ myprod.title }}
    {% endfor %}
  </div>
</section>

<section>
  <h2>Collection and Metaobject</h2>
  <p>Product gets an author metaobject *and* a collection...</p>

  No apparent advantages!
</section>

<section>
  <h2>Metaobject Only...</h2>

  WORKS, but can't filter on array of products...

  {% assign authors = shop.metaobjects.author.values | where: 'first_name', 'Charles' | where: 'last_name' includes 'Dickens' %}

  {% for author in authors %}
    {{ author.first_name.value }}
    {{ author.last_name.value }}
  {% endfor %}

  WON'T WORK!
