`first` and `last` work inside a path, `{% dump %}` and `json` print the values of objects, and a missing metafield is nil.

***

# Paths

* `first` and `last` can sit in the middle of a path, for example `collection.products.first.name`.
* `map` and `sort` read properties of objects, for example `product.variants | map: 'price'`.

# Output

* `{% dump %}` and `json` print the fields of an object, such as metafields and related products, instead of `{}`.

# Metafields

* A metafield namespace or key that does not exist is nil, so `{% if product.metafields.reviews.rating %}` is false when the product has no `reviews.rating` metafield.
