I have been an avid proponent of the way errors are managed in Rust and Go for a long time. However, this article raises a very good point. Before i started developing in Rust and Go, i did Java and python for several years. And damn, do i miss those stacktraces every now and then when something bad happens that isn't properly handled by the code.

Still, i do think returning the error as a return value is better than having a completely separate flow when dealing with exceptions. I like that it forces me to properly deal with an error and not just ignore it and think something like "meh, i'll get to this later". Because i will never "get to it later".

You could combine both by adding a stack frame each time the error is returned one level up. This could be done explicitly (cumbersome and not everyone will do it) or automatically by the language (weird magic, but useful).
