This _is_ kind of fun. Your demo suggests that maybe rake and dependency
injection can be unified somehow.... For example, using my favorite DI toy:

----
require 'mindi'

class Tasks
  extend MinDI::Container

  a  { puts "a"; :done }
  b  { a; puts "b"; :done }
  c  { a; puts "c"; :done }
  d  { b; c; puts "d"; :done }
end

Tasks.new.d
----

Output:

a
b
c
d

(The ":done" could be removed if MinDI didn't confuse a nil return value
with the state of not yet having been called.)
