    In Elixir, we mark statuses by using a question mark at the end of the variable name. Something like this:

    authorized? = user |> get_something() |> ensure_authorized?()
    

    I like this better than the is_ prefix

        If it’s like Lisp, then ? is just part of the symbol and doesn’t have any special syntatic meaning. In different Lisps it’s also convention to end predicate names with a ? or with P (p for predicate)

        We do this in Ruby all the time, we just prefer methods over variables, usually.

        def authorized?
          current_user&.authorized?
        end

          I’m a principal backend engineer routinely writing Ruby for my day job, so I’m familiar, lol. But you can’t do it for local variables and that just sucks. Definitely a +1 for Elixir.
