# If you want to include both 0 and 9, you can use upto instead 
# of times:

yes, and the fun part of ruby is that you can create your own and be creative as much as you like, too;  a simple example

irb(main):025:0> class Integer
irb(main):026:1>   def mytimes start=0,inc=1
irb(main):027:2>     x=start
irb(main):028:2>     cnt=self
irb(main):029:2>     while cnt > 0
irb(main):030:3>       yield x
irb(main):031:3>       x+=inc
irb(main):032:3>       cnt-=1
irb(main):033:3>     end
irb(main):034:2>   end
irb(main):035:1> end
=> nil
