I have had this kind of problem a few times. In most cases, upon reflecting more, it was a symptom of some logic that needed to be extracted. Sometimes I ended up extracting the shared logic into a private function used by several handle_call clauses, and some other times I even ended up extracting it in its own module. The second option can also result in easier testing, and can be called from a Task (or other construct) if necessary, separating functional logic from runtime concerns.
