You are right, I am sorry :-)
In D the name of functions starts with lowercase.
class Fib {
private const Fib left, right;
this(in Fib left=null, in Fib right=null) {
this.left = left;
this.right = right;
}
const int evaluate() {
if (left is null)
return 1;
else
return left.evaluate() + right.evaluate();
}
}
Fib bar(int n) {
if (n == 0 || n == 1)
return new Fib();
else
return new Fib(bar(n - 1), bar(n - 2));
}
void main() {
auto x = bar(5);
assert(x.evaluate() == 8);
}
