``` Ruby
class Latch # Maybe no the best name
  def flipped?; !!@flipped end
  def flip!; @flipped = true end
end

# Somewhere
@configuration.seed_latch = Latch.new

# Random class has access to configuration, it can do
@configuration.seed_latch.flip!

# UI has access to configuration, it can do
@configuration.seed_latch.flipped?
