So, this is a place I don't seen any value in using lambdas:

```ruby
let(:serialized_result) { serializer.to_media_type }

after do
  expect(@result_element).to eq(@document_element)
end

it 'returns the correct link method' do
  @result_element =  serialized_result["_links"]['author'][:method]
  @document_element = document[:transitions].first[:method]
end

# Etc.
```
Am I missing something? Could name the local vars to be more self-describing as pertinent.
