Could someone recommend me a paper that discusses the relation between
Girard's System F and Hindley-Milner type systems? I've been studying
system F lately (and Haskell's semantics is still somewhat mysterious
to me), and in System F existential types can be built from the basic
operations, while in Haskell it seems that one needs language
extensions to be able to use them...
Thanks & cheers,
