You can't declare it directly. Instead, you allocate the hashes as you 
go along, or pre-allocate them if you know how big the array will be:

   SIZE = 100
   a = Array.new(SIZE)

   SIZE.times { |i|  a[i] = Hash.new }


--or--

   a = []

   # then later

   a[i] ||= Hash.new
   a[i]['joe'] = ...


There's a rumor that the next version of Ruby will feature active
defaults, allowing you to do this kind of thing automatically.
