I’ve noticed that when you include `Do::All` module into a class it makes every methods defined in this class publicly available. Is it a bug or intentional behaviour?

Consider following example:  
[GitHub Gist](https://gist.github.com/WojciechKo/d40cf9b040b25e287794dbc1cf88a029)

```
require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem 'dry-monads', '1.3.5'
  gem 'rspec', '3.9.0'
end

require 'dry-monads'

class Service
  include Dry::Monads[:result, :do]

  def call
    yield fetch_data
  end

  private

  def fetch_data
    Success(:data)
  end
end

RSpec.describe Service do
  subject(:service) { Service.new }

  describe '#call' do
    it 'returns data' do
      expect(service.call).to eq(:data)
    end
  end

  describe '#fetch_data' do
    it 'raises NoMethodError' do
      expect { service.fetch_data }.to raise_error(NoMethodError)
    end
  end
end

RSpec::Core::Runner.run(['spec', '--format', 'doc'])
