def view_paths=(paths)
  @view_paths = ActionView::PathSet.new(Array(paths))

  added_resolvers = 0
  self.class.fallbacks.each do |resolver|
    next if view_paths.include?(resolver)
    view_paths.push(resolver)
    added_resolvers += 1
  end
  yield
ensure
  added_resolvers.times { view_paths.pop }
