Bulat, I think existential types somehow correspond to the idea of *subtyping* (as illustrated in the Existential type page, hope you can elaborate on that.
subtyping possible without existensuials, it's just "=>" in "class" declaration. as both me and John said, existensials just packs dictionary togehther with object what makes possible polymorphic lists and so on, i.e. using different _instances_ of the same class inside one list or other container, or in different arguments in function, Bulatz 15:14, 18 August 2006 (UTC)
This is written in the first person in places, which makes it difficult to collaborate on. —Ashley Y 09:25, 27 August 2006 (UTC)
