When an event-fx dispatches to an event-db, pull the event-db's op to the original event-fx and change it to event-db
In Re-Frame, I removed effect events for db events. Pure db events represent low cognitive-overhead functional programming: db in, db out. Side effect fx events necessarily complicate the program, but per Jacek Schae’s instruction, I removed unnecessary cases: I.e. fx events that dispatched to db events. I changed these db-dispatching fx events to a db event and have it modify the db one more time in a db event instead of dispatching. This is apparently more pure and therefore better.
