Internal references are not exposed precisely because user code shouldn't depend on it. If you want forever-valid references to container members, just store references to your data instead of the data itself, e.g., MyStruct*[] (as long as you make sure your structs are allocated on the heap). Or use classes, which are reference types, e.g., elements of MyClass[] will be "forever valid". T -- The richest man is not he who has the most, but he who needs the least.
