  # The original version of this type treated initialisation with an integer
  # value of zero as invalid, setting the initialised range to (-1..-1). On
  # reflection, this makes little sense as a general-purpose behaviour, as it is
  # highly likely to surprise casual users.

      value.min..value.max
