If you mean by this, "static typing is not worth the effort", the zeitgeist is definitely not with you on this one.

> There's honestly no need for static typing in Elixir.

I'd love for that to to be the case! Is the only way for me to find out for me to give it a try, or are there somethings you can say to help me believe?

Yes, that's definitely what I mean. I've never much cared for the zeitgeist. I care about a reasonable rate of return.

If you care about static type checking, Erlang/Elixir actually has an opt-in thing called Dyalizer that lets you annotate functions and then traces the types through. I've never even tried it though, because I never felt the need for static typing.
