Subject: Re: ruby idiom for python's for/else while/else

Here's another:

(2...10).each do |n|
  unless (2...n).any? do |x|
           if n % x == 0
             puts "#{n} equals #{x} * #{n/x}"
             true
           end #else nil
         end
    puts "#{n} is a prime number"
  end
end

But, really, I'd rather write it like William Morgan did.
