Ridiculous.  You would never compact an array just to get the first 
element.  If you want the first element, then grab it.  See Bertram's 
posts.

If the length of the string will always be a multiple of 3, you can do 
this:

str = "a9digh0t5"

str.scan(/.{3}/) do |substr|
  puts substr
end

--output:--
a9d
igh
0t5


Otherwise, you'll have to deal with ruby's infernal each_byte() method.
