Would it not be nice to simply extend the behavior of String#each e.g. like
this

"Really nothing intelligent to tell".each <some_intelligent_choice> do
          |c|
          puts c
end
=3D=3D>
R
e
etc. etc.

<some_intelligent_choice> might be 1 (imagine what n could do!)
 [ we could even formulate endless loops like this
   "".each 0 do
    puts "Eternity is a hack of a long time"
   end
 that is *really* great ;)
]
or shall everybody do it oneself

class String
      def my_iterator ....

I just do not think so.

Cheers
Robert
