It seems to me like this _should_ be something that Rubocop repots on, though. I overlooked reporting this as an offense, which I can fix. I can also appreciate that it may be a separate concern from this one, in which case I suppose I could move it to its own cop.

The following seems like a completely undesirable thing to allow:

```ruby
foo(:param) do |bar| some_method
  baz
end
```

Also, from the perspective of a real-world use case -- in our codebase we had a lot of blocks like this:
```ruby
let(:foo) { create(:factory,
                   attribute: 'blah') }
```

This correction was critical to changing our code so it looked halfway decent while also conforming to Rubocop guidelines.
