1) write if (left is null) instead if checking for null. Equality
operator is rewritten to a.opEquals(b), which you don't want if you
checking for null.

2) default constructor as you written it is not needed, fields are always
initialized to default value of their type, which is in this case null.

3) Classes in D are reference types. It should be
private const Fib left, right;
4) second constructor - Classes in D are reference types, & operator is
not needed (see point 3), parameter left and right are already references
