I made a PR to fix throw compilation. For the raise example, it expects either a string or a module/atom which it calls exception on. So the above would not work. https://hexdocs.pm/elixir/Kernel.html#raise/1

bad example

raise("atomm")

Uncaught Tuple {values: Array(2), length: 2}

Its not very informative, perhaps can be improved to look like an actual raise occured?

Errors should definitely be improved. Raise eventually calls :erlang.error passing to it the result of Exception.exception/1. The implementation of erlang.error can be improved to show errors that look closer to what is expected

Reopening so discussion is seen

Error messages from raise or :erlang.error should now look like ones from Elixir
