Subject: Re: iterate chars in a string

"I am puzzled".each_byte { |b| puts b.chr }

I'm surprised that not many people knew about 'each_byte()'.  Maybe it's a 
problem with Ruby docs?  Or maybe it is just counter-intuitive - I would expect 
each() iterate over bytes, and provide each_lines() to iterate over lines instead.
