If I have type T1: Into<E1>, and type T2: Into<E2>, I can't seem get something like this to compile:

fn func() -> Result<Result<T, E1>, E2> {
  function1()?;
  function2()?;
  Ok((T::new()))
}

where fn function1() -> Result<(), T1>, and fn function2() -> Result<(), T2>.

Maybe I am asking too much from the ? operator.

Is the only way to make this work to match on all calls that could return an error, and return the properly formed Ok(Err(E1)) or Err(E2)?
