Thank you for the changes, Tom!

I believe you can alias `ip` with `it2` using `ip => it2(index)`.

Aliasing `ip` with `rt` does not seem possible to me, though `complex` pointer/target variables may alias with `real` pointer variables (e.g. when `%re` or `%im` part designator is used in pointer assignment).
