(What are existential types? I've understood it a number of times and occasionally I discover a pattern I'm looking for while programming is an existential type, but I still don't understand them well enough to tell you the transformation from forall to existential types. Haskell lacks them in part because using that transformation means you can write existential in terms of forall, but they're still useful.)
