Rescript frustration

i actually did give examples, but ok:

with while-let:

while let Some(data) = dataReader.read() {
  // ...
}

vs

let done = ref(false) // also is a useless alloc unless rescript is optimizing that away, unsure
while !done.contents {
  switch dataReader.read() {
  | Some(data) => // ...
  | None => done := true
  }
}

it’s ridiculously convoluted just because we have neither while-let, if-let, break or return.

EDIT: also keep in mind that the above is just one trivial example, you’re going to have nested instances of the above in all sorts of different forms in any real-life code base with a few tens of thousands of lines in it.
