Hi! I have a bunch of `Maybe`'s and I'd like to log when some of them complete without emitting an item. Is this possible somehow? I need a variant of `doOnComplete()` which is invoked only when Maybe is empty...

Turn into an Observable and multicast it, where one observer uses count() to see if it's 0?

Well, that would be to much for me. I just need a simple side-effecting `doOnEmpty()`

Hah! According to RxJava's github, `Maybe.doOnComplete()` actually executes *only* on empty `Maybe`. If `Maybe` emits and item, `doOnSuccess()` should be used.
