Merge tuples types

at some point, you have to consume these results, so you have to know the dimension of your tuple and its inner types. What is the problem here? Is it about having tuples of dynamic size (which you can’t have), or is it that the combine function is too cumbersome?

If it’s the latter, you could combine them in a better manner:

let combine8 = (
  a: ReactFirehooks.Firestore.queryResult<'a>,
  b: ReactFirehooks.Firestore.queryResult<'b>,
  c: ReactFirehooks.Firestore.queryResult<'c>,
  d: ReactFirehooks.Firestore.queryResult<'d>,
  e: ReactFirehooks.Firestore.queryResult<'e>,
  f: ReactFirehooks.Firestore.queryResult<'f>,
  g: ReactFirehooks.Firestore.queryResult<'g>,
  h: ReactFirehooks.Firestore.queryResult<'h>,
) => {
  switch (combine7(a, b, c, d, e, f, g), h) {
  | (Loading, _)
  | (_, (_, true, _)) =>
    Loading
  | (Error(error), _)
  | (_, (_, _, Some(error))) =>
    Error(error)
  | (Data((qsA, qsB, qsC, qsD, qsE, qsF, qsG)), (Some(qsH), _, _)) =>
    Data((qsA, qsB, qsC, qsD, qsE, qsF, qsG, qsH))
  | _ => Unknown
  }
}
