I think I prefer this style for things like factories and stubs, where there is a single identifying argument followed by a Hash of options:

```ruby
foo = create(:something, {
  bar: 1,
  baz: 1
})
```

The alternative blurs the boundary between the identifier and the attributes:

```ruby
foo = create(
  :something,
  bar: 1,
  baz: 1
)
```

I don't think I'm violating the thoughtbot style guide here, just using some punctuation that could be omitted. I could also omit parentheses on many method calls where I choose not to.
