Thanks Nathan!

The new macro sounds OK to me. Perhaps we should add some docs to the
other two attributes about their relationship and/or the existence of
this new `__always_used` one (so that it is easier to find). And if
so, then perhaps the docs for `__always_used` can be simplified.

Yeah, since the `unused` one only applies to that, right?
