Hi Joe,

When these classes were designed several years ago, we were under pressure
to not derive these kind of classes from TObject. A posteriori, I agree
that this was probably a mistake. There are many more advantages in deriving
from TObject (consistent framework behaviour) than disadvantages.
We cannot change these classes now.
However, you can use alternative classes such as TVectorD that derive
from TObject.
