Hm. Without any context, the claim that the above is or is not bad
design cannot be made. Since T2 is derived, would a access to base
type be more appropriate? Is T2 really an extension or should it be
incorporated in T1? What is the purpose and how will they be used?

C makes it easy for you to shoot yourself in the foot. C++ makes that
harder, but when you do, it blows away your whole leg.
