I Think override makes perfect sense in this case.

I get to only implement the GetCurrent procedure once, the example is 
simplified but in my real-world application it does some additional 
structure checking, and in all derived classes i get to call the 
ancestor method but return an object of the type i need.

If I could not override the code for GetCurrent the following

forBar inBarList do
     Bar.Val2:=1;

would not be able to know the Bar is a TBar, but would rather see Bar as 
a pointer (since in this case it inherits from TList). And all 
subsequent code would have to do some sort of typecasting.

I hope that makes a little bit of sense...

Torsten.
