Actually, it's much easier than that.

The following bit of code synthesizes creates 10 tasks where task t(n)
depends on t(n-1), except for t0 which depends on nothing:

     task :t0

     (1..9).each do |i|
       task "t#{i}" => "t#{i-1}" do |t|
         puts t.name
       end
     end

No need to delve into define_task and all that.
