Yeah, I don't like it either -- I reflexively did it because in the
safety series I am sending, there was a case where it would not notice
the `// SAFETY` comment if an attribute was placed afterwards.

But for blocks like this works fine, so it is not needed here, so we
can change it, even we may need to be inconsistent in a few places
about this, at least until it is fixed (assuming it is indeed a false
positive).

I created an issue in Clippy about it:

Thanks!

Cheers,
Miguel
