Testing closure-based chains with assertChained?

[michael-rubel]

I have a bus chain partially based on closures:

Bus::chain([
    new MyFirstJob,
    fn () => Bus::batch()...

How can I test that closure was executed in the chain?

Something like this:

Bus::assertChained([
    new MyFirstJob,
    new AnonymousChainClosure,
]);

Looks like this feature is missing.
