Duh. I can just use the Array.new, and append a .join at the end to get 
the random string. And Axel, I'm generating quite a lot of arrays in my 
small prog, and using this shorter way makes it indeed clearer :). It is 
definitly worth it.

Example:


   filter = Array.new(WINDOW) { bucket = Array.new(AMINO) {|i| (97 + 
i).chr} }

was

   filter = []
   WINDOW.times {bucket = [] ; AMINO.times {|i| bucket << (97 + i).chr} 
; filter << bucket}
