Agree this is a good pattern. Im not categorically against throwing errors but I like returning errors or the result and then having to check at the caller. Do this in typescript a lot.

Any typed language could use this pattern, though with Elixir specifically it was idiomized from the very beginning and all libraries use it, which makes error handling very consistent even when piping operations. The common option to fail fast is also handy when crashing the process is preferred and no matching is required to unwrap the value
