Oh right. A clear solution that didn;t even occur to me (duh). But
that's probably b/c you are right. At that point it gets too Lispy. I
really would like a way to do it in the code of the method somehow
though. As I mentioned, using memoize get very close to such a
solution, but the trick is it has to be a sort of "relative cache" i.e.
cacheing in a sort of namespace relative to the initiating task. And I
don't know if that's possible. I imagine trying to control it with
something lije this:

  task :t7 do
    preq { t1; t2; t4("one", "two"); t6 }
    ...
  end

But how would one monitor which methods have been executed?
