Subject: Re: implementing the "each" method for own classes

actually i did test it with a queue filled with a few elements. as you
said the condition for the while loop should be testet at the
beginning, otherwise nil could be returned.
so my code looks like this:

def each
  node=@head
  while node=node.next
   yield node.content
  end
end

do you have an example for the second remark, as i don't quite
understand what you mean

thanks,
philipp
