pub fn main() -> Nil {
  let assert Ok(_) =
    fiction.new()
    // collect all environment variables with a prefix,
    // using the unprefixed and lowercased name as the key for the value (eg. APP_FOO -> foo)
    |> fiction.join(env.prefixed("APP_"))
    // try to get values from a list of names
    // if a value is available the key will be the lowercased name (eg. FOO -> foo)
    |> fiction.join(env.exact(["FOO", "BAR"]))
    |> fiction.extract(..)
