Why no decreasing enumerations?

If you actually have to do this task all the time, you could define your
own Integer#to method:

···

####
class Integer

  def to limit, &block
    if self <= limit
      upto limit, &block
    else
      downto limit, &block
    end
  end

end

10.to 1 do |i|
  puts i
end
####

I wonder why *that* isn't already in Ruby. :wink:

Have you proposed it to ruby-core@?

This is a feature I've implemented several times myself as well and would seem to be useful to have in core. Ryan, what is the recommended way of making these proposals? Just post a message to the ruby-core mailing list? Open a ticket? Do we still have some sort of RCRchive?

It's been a while since I've asked for something in Ruby :slight_smile:
