Pattern matching is one of the best superpowers that erlang/elixir have. We should not try to decorate/hide pattern matching with other stuff by adding more magic. I agree that having more expressive atoms may be helpful, but this may not be the best way to go about it, See Usage of {:ok, result} / :error vs {:some, result} / :none . To me it seems like we are adding more noise without giving the user much in return.
