I think I have mentioned that in another context, but the standard seems
to be to use `interop.rs` instead of `interop/mod.rs` (Miguel please
correct me if I'm wrong).

Also, and once again, please, please build with CLIPPY=1 before sending.
The buddy series also has clippy warnings. Fixing them before I can
review is tedious.
