Ruby: make ranges always include the last value (See related posts)

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
