Strategy for visible errors with Rxjs

Hi, I find errors very hard to troubleshoot mainly because rxjs will silently swallow and "fix" them (with the tryCatch wrapper, removing handlers etc. This renders some epics dormant without any visible error to indicate) https://github.com/ReactiveX/rxjs/blob/01a09789a0a9484c368b7bd6ed37f94d25490a00/src/internal/util/tryCatch.ts

Other than activating break on exceptions, do anyone have a better workflow?
