Subject: Re: Putting some code out to DRY


|        seed = @start
|        whatever = lambda do
|          yield(seed)
|          @skip.times { seed = seed.succ }
|          return if @halt.call(seed) if @halt
|        end
|        @step ? @step.times(&whatever) : loop(&whatever)
|      end


FYI: I ended up using this lambda approach after all. Many thanks to those who 
suggested it.

I occurs to me that this also has to do with 1st class methods. An (as of yet) 
untested possibility:

  ( @step ? @step.method(:times) : method(:loop) ).call proc do
     yield(seed)
     @skip.times { seed = seed.succ }
     return if @halt.call(seed) if @halt
  end
