We've stubbed a variety of modules and the functions they expose, but none of the stubs warn that they're stubbly, which is dangerous, because it makes them easy to overlook when troubleshooting an issue that may be caused by an incomplete or missing implementation.
So we should make those stubs warn (once per session) when the stubbed modules are evaluated and the stubbed functions are invoked.
