Review comment:
You need to return the pointer instance here so that the pointer methods can
satisfy the interface.
Value methods are "promoted" to the derived pointer type, but not the other
way around.
From Effective Go:
The rule about pointers vs. values for receivers is that value methods can
be invoked on pointers and values, but pointer methods can only be invoked on
pointers.
