File metadata via statx with ergonomic accessors. Uses the Exception effect for error handling.

Example

{ metadata } :: import "std/fs/metadata";

main :: (fn(using(io : IO)) -> unit)({
  given(exn) : Exception = {
    throw : (fn(forall(T : Type), error: AnyError) -> T)(
      { println(error.to_string()); exit(i32(1)); }
    )
  };

  m := io.await(metadata(Path.new(`/tmp/test.txt`)));
  printf("size: %lld\n", m.size());
  printf("is file: %d\n", i32(m.is_file()));
});
