I’ve written a little utility for creating functional command objects without boilerplate, and using DI via constructor injection (without going the full bore container route). Would love feedback on the interface:

class CreateUser

  extend CommandObject

  dependencies user_repo: UserRepo, email_service: MyEmailService
  input :name, :email, :password
  steps(
    :validate_input,
    :ensure_unique_email,
    :insert_user,
    :send_confirmation
  )

  private
  #
  # implementation methods here...
end

# Used like:
create_user = CreateUser.new
create_user.(name: 'John', email: 'john@gmail.com', password: 'secret')
