That is an option sometimes, yeah, but in this case, writing those
lines is also a burden -- one that is, I would say, worse than just
using `()`.

It would also need to be `allow` here, not `expect`, because older
versions do not complain, which makes it even worse...

So it is all about what a lint gives us in exchange of those false
positives, and about how much time people would need to spend on it. I
have always supported adding lints (I think I added this one, long
ago, in fact), but I don't want that we overdo it either, so I am
happy disabling it if it is going to be too painful.

Cheers,
Miguel
