Yes. you are right, sir Pit. Thank you for the explanation.
To give example, currently the family do it like this:
irb(main):011:0> class Integer
irb(main):012:1> def new_times start=0, step=1
irb(main):013:2> x=start
irb(main):014:2> self.times { |i|
irb(main):015:3* yield x
irb(main):016:3> x += step
irb(main):017:3> }
irb(main):018:2> end
irb(main):019:1> end
=> nil
# note the use of #times with #new_times above to emphasize
# similarity and suggested change
irb(main):020:0> 5.new_times {|x| p x}

irb(main):021:0> 5.new_times(1) {|x| p x}
