(App f x) = (f x)
(Succ x) = (+ x 1)
(Main) = (Pair (App Succ 0) (App @x(Succ x) 0))

This HVM code reduces (Main) to (Pair ((Succ) 0) 1). I would intuitively expect (Pair 1 1).

My understanding for this is that in (App Succ 0), the expression Succ is actually shorthand for (Succ), so we have (App (Succ) 0) which reduces to ((Succ) 0) which does not reduce.
