(Protocol.UndefinedError) protocol List.Chars not implemented for {:error, :bad_name}

[Munksgaard]

When using the initial example from the README to the main/1 of an escript, building with mix escript.build and running the resulting executable, I get the following error:

** (Protocol.UndefinedError) protocol List.Chars not implemented for {:error, :bad_name} of type Tuple. This protocol is implemented for the following type(s): Atom, BitString, Float, Integer, List

Here's the module I've defined:

defmodule Foo do
  def main(args \\ []) do
    list = Enum.to_list(1..10_000)
    map_fun = fn i -> [i, i * i] end

    Benchee.run(
      %{
        "flat_map" => fn -> Enum.flat_map(list, map_fun) end,
        "map.flatten" => fn -> list |> Enum.map(map_fun) |> List.flatten() end
      },
      time: 10,
      memory_time: 2
    )
  end
end

I am using elixir 1.14.3 and OPT 25.

EEEEEEK

thanks for the report 💚 Also, sorry for the long down time. Lots of going on.

Me and escripts 😂 Let me see if I can reproduce and figure this one out

Reproduced!

Alright, that's just a procol consolidation check that may or may not still be relevant that fails on looking up the elixir executable I can probably fix this easily or at least circumvent it

No worries! I appreciate the work you're doing ❤️

And fixed on main via #395 ! Thanks again for the report!
