Sven, I missed this post when you made it a two days ago. If someone hasn't already asked, does your implementation support short circuit evaluation?
For example: BasketCount := IfThen(ShoppingList <> nil, ShoppingList.Count, 0); Where evaluating ShoppingList.Count will cause an exception if ShoppingList is nil. Also the reverse should short circuit as well: BasketCount := IfThen(ShoppingList = nil, 0, ShoppingList.Count);
