"Use subject"

What are your thoughts on https://evenbetterspecs.github.io/#use-subject?

I think this bit

describe '#add' do
  it 'sums two numbers' do
    subject = described_class.new(5)

    expect(subject.add(1, 2)).to eq(8)
  end
end

should be

describe '#add' do
  subject { described_class.new(5) }

  it 'sums two numbers' do
    expect(subject.add(1, 2)).to eq(8)
  end
end

to follow the RSpec docs on explicit subjects.

the drawback of this approach is that if you need to pass a variable to described_class.new you would need to use let/let! - which are not recommended
