No escape hatch for typing error

I’m currently migrating my codebase to Elixir 1.18.2. I was able to solve all the typing issues, except for one. The following code:

defmodule Run do
  def test do
    try do
      Code.compile_string("a + ")
    rescue
      e ->
        case e do
          %{column: column, snippet: %{offset: offset}} ->
            {:error, column + offset}

          _ ->
            {:error, :unknown}
        end
    end
  end
end

Gives me the following compilation warning:

This could be solved by adding guards, that will allow for infering the types in a future release. But at the moment I’m not able to migrate this code and there is no scapehatch for it.
