Hm, replacing the return with a random string, this leads to another crash:
Traceback (most recent call last):

The reason is that `__getattr__` is also triggered when a special attribute is looked up. I am not sure what to do with this. This is a bit inconsistent with how classes behave, where e.g. `__len__` is never searched on an instance. But modules are special in many other ways, so maybe we can just fix pydoc (and other tools like inspect) to expect some ill-typed values in special module attributes and fail gracefully? |
