The computation for determining the shapes to use at the top of getInstantation was not always creating shapes with the proper indexes. If an instantiation is being called from another instantiated function, we cannot just copy the shape types unchanged, because their indexes may have changed. So, for type args that already shapes, we still call Shapify() with the correct index.
