def [](type = nil)
  selected = @parent.now.select do |hash|
    condition(hash, type: type, scope: @scope)
  end
  # p 'flash[]', type, @scope, selected
  selected.map { |hash| hash[:text] }
end

#[]=(type, text) ⇒ Object

We assign to the next hash, but retrieve values from the now hash. Freaky, huh?
