Responds to the object itself

I want to respond to the specified object itself.

If you program as follows, you will get an error with no body method.

class BodyEntity < Grape::ENtity
  expose :body
end

get do
  present 'success', with: Entities::BodyEntity
end

As a workaround, we currently program as follows.

class BodyEntity < Grape::ENtity
  expose :body do |body|
     body
  end
end

get do
  present 'success', with: Entities::BodyEntity
end

Is not there a better way?

Start by reproducing the shown Grape::Entity class with expose :body and the present call, then compare it with the workaround that returns body explicitly. The work is done when the specified object itself can be presented without requiring that workaround; the issue does not name a file or test to update.
