But the point of Haskell is to provide an abstraction that hides these
details from you. (Though ultimately it's a leaky abstraction and
there comes a point where you do need to know about these things.)

I'd second that. It's hard to see the difference between declarative
and imperative programming when you only have one instance of a
declarative language from which to generalise.
