This looks fishy:

class Fib
	private const Fib* left, right;
	this(in Fib left, in Fib right)
		this.left = &left;
		this.right = &right;

Are you sure you want a pointer to class? Classes have reference semantics  
in D (like Java). Structs are value types, though. Anyway, it looks like  
the ctor takes the address of the reference placed on the stack.
