Added it to our API review for today...thanks!

Sorry - we didn't get to it in API review this week. But at a high level, I
like the concept.

No worries. Would it be better to defer work on this until after it is addressed in review?

@benjamin-bader Yep - let's hold off until it's greenlit @ API review. Thanks!

Looks like we never ended up discussing this, but I think we'd like to hear a bit more about the use-case you had in mind?

from truth.

Sure. The impetus for me was writing some Jersey Injectable implementations which, to be automatically registered with the runtime, must be annotated with @Provider. I think assertThat(klass).isAnnotatedWith(Provider.class) reads much more nicely than assert_().that(anno).named("has @Provider").isNotNull().

Since then, I've been playing around with generated classes and wishing to ensure that they have the expected annotations, but that's a decidedly more unusual case (for me, at least).

The important point to me is that there are cases where a missing or incorrect annotation will cause incorrect behavior at runtime, but whose absence/misuse will not be caught by the compiler - therefore requiring test coverage.
