Comment:
Poking about at this some more, I think it is possible to serialize the
validator in my example, because the `validate_max_words(300)` returns a
function object that has a `__closure__` attribute which contains bindings
to the environment in which the function object was created.
I'm not sure though how reliable this would be for less simple examples,
and given how easy it is to work around, I think the new error message is
good enough.
