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
]
