Python 3.11: “Zero cost” exception handling

You may enjoy programming in Elixir if you like that style. In Elixir, you only program the “happy path” and just let things fail. Then you rely on supervisor processes to handle the exceptions/errors. Well, at least that is the idea. I think people still do tests and function guards and things. but the “let it fail” idea is definitely part of the Erlang/Elixir world.

The sad thing is that there really isn’t any “learn elixir” book that teaches this idiomatic design. A student of Elixir should set up an umbrella application from the very first hello world, in my opinion.

Well, I don't enjoy the "happy path" programming. Admittedly, this implementation to improve speed feels a bit hacky. I only did it because it had a measurable impact on the computational performance of my program. In my other grunt worker scripts, I actually prefer if-elif-else statements because they make code readability better for other programmers who are not Python "natives", but use the scripts or modify them to suit their use cases.
