Thanks for updating the error message, Hannes. This PR adds tests for 2 out of
6 items from your list. I think it makes sense to ensure that the remaining 4
items are also tested. I can see that one more item is covered by the existing
RefBadParens. That said, I couldn't find tests that cover these 3 cases:
#foo(int
#foo(int)x
F<T
