Interfaces do not hold interface values. What this means is that when you write "a = b" where a and b are both of interface type, then the value that is in b will be copied to a. a will wind up with the dynamic type and dynamic value that were originally in b. The dynamic type of a will not become the type of b; it will become the dynamic type of the value stored in b.
