There shouldn't be anything quadratic left for template instantiation in the frontend.
Maybe not for a single instantiation, but constructing the module member list is overall still quadratic in the number of members (which might be quite a lot if you heavily use templates, because all the instances get added first, whether they make it to codegen or not).
