  # This allows us to expose `render_views` as a config option even though it

  # command (i.e. `render_views = true`), where it would normally be used
  # as a getter. This makes it easier for rspec-rails users because we use
  # `render_views` directly in example groups, so this aligns the two APIs,
  # but requires this workaround:
