I have a pattern that's working really well for us in the codebase, which I call `recover`. Anywhere where you're tempted to crash because it's not possible, I add recover debug_string debug_values return_value Recover prints a stack trace, notifies Rollbar, and then continues with the return value. As a result, we see whatever is going wrong with the code, but the program doesn't crash on users. And since we're using OCaml (strongly typed), we end up having decent guarantees of safety. Works pretty well for us.
