  local!numberOne: 17,
  local!numberTwo: 5,
  if(
    local!numberOne = local!numberTwo,
    {},
    a!localVariables(
      local!lowerNumber: min(
        local!numberOne,
        local!numberTwo
      ),
      local!upperNumber: max(
        local!numberOne,
        local!numberTwo
      ),
      local!difference: local!upperNumber - local!lowerNumber - 1,
      1 + local!lowerNumber + enumerate(local!difference)
    )
  )
