Defexception ... functions overridable?
I’m just discovering defexception but I think the docs are not correct (?). It says " The Exception (Exception — Elixir v1.20.2) behaviour requires two functions to be implemented: exception/1 and message/1" — but I think only the message/1 needs to be implemented. Is this correct?
First Post!

It’s correct. The behaviour requires it, and the defexception macro gives you a default implementation; agreed that the verbiage is slightly confusing.
