(add-hook '1-arity-functions 'some-zero-arity-function)
(run-hooks '1-arity-functions some-arg)
Here, it will throw an error because run-hooks will try to call
(some-zero-arity-function some-arg). That's all fine and well
documented, I'm just saying it may be more convenient if run-hooks
took care to check that some-zero-arity-function has zero arity and
invoked it without arguments.
