Ruby: make ranges always include the last value

So, in conjunction with other snipped about setting up intervals on Time, this can be added to Range to make sure it always includes the last value, even if the interval doesn't directly land you on the end value

class Range
  def each(options = {}, &block)
    val = self.begin
    while val < self.end
      yield val
      val = val.succ
    end
    yield self.end if self.end == val || options[:always_include_last]
  end
end

Ruby: set an interval for your Time (useful for ranges, especially)

class Time
  def set_interval(seconds)
    @interval = seconds
  end
  def succ
    @interval ||= 1
    ret = self + @interval
    ret.set_interval(@interval)
    ret
  end
end
