   "hello".bytes.to_a        #=> [104, 101, 108, 108, 111]

/*
 *  call-seq:
 *     str.each_byte {|fixnum| block }    => str
 *  
 *  Passes each byte in <i>str</i> to the given block.
 *     
 *     "hello".each_byte {|c| print c, ' ' }
 *     
 *  <em>produces:</em>
 *     
 *     104 101 108 108 111
