Subject: Re: how to double single quote (beginner blockage)

And what if the input string correctly contains double quotes?? ;-)

String doesn't have a each_with_index method.

class String
  def each_with_index
    counter = 0
    each_byte do |char|
      yield char, counter
      counter += 1
    end
  end
end

"abc".each_with_index do |char, index|
  puts char.chr + ' ' + index.to_s
end

Please note that char is an integer, so you have to call char.chr.

Untested, but it should work.
