[Haskell-cafe] policy for new packages

Hi guys, In my software I developped some piece of code that I think are sufficiently generic to be useful for others (some datatypes and typeclasses). Should I put them in a separate package and annonce them? What is the best pratice here? Namely it's a datatype called Data.Todo allowing to keep track of actions left to do to complete a computation, and the other is a typeclass called Control.Shortcut designed for computations that can be run in parralel and shortcuted if necessary. So they are small (but useful) things, I'm wondering if creating one package for each is worth it, or another policy can apply. Cheers, Corentin
