Try doing this in C++:
type 'a node = Leaf of 'a | Unop of ('a->'a) * node | Binop of ('a *
'a -> 'a)
let rec eval n = match n with
| Leaf i -> i
| Unop (f,n) -> f (eval n)
| Binop (f,n1,n2) -> f ((eval n1), (eval n2))
[Hint: it cannot be done without one of:
a) casts, or
b) serious difficulties wth memory management
]
