Hash within an inline block

  I miss this in the guide:

```ruby
  # bad
  let(:foo) { { bar: 2 } }

  # good
  let(:foo) {{ bar: 2 }}
```

...or if you want other way around

```ruby
  # bad
  let(:foo) {{ bar: 2 }}

  # good
  let(:foo) { { bar: 2 } }
```

I like first more, but I go with whatever, as long as it's in the guide

thx
