Hi Christian, the only safe (meaning: consistent) question is: what is the next message that I have received. That there is a mailbox that may hold multiple of them is not really relevant because you cannot safely reason about its contents—everything outside of an actor is concurrent and non-deterministic. In addition, Actors are all about state, modeling state in a distributed setting is their only purpose. Dropping some messages while not dropping others of the same quality surely is a stateful activity.
So, yes, one could be tempted to give low-level access to the mailbox data structure for various reasons, but in all cases that has been a bad idea in the past, and I am pretty certain that extrapolation into the future is valid.
