pipe(fn)
.of(x).pipe(withLatestFrom(...args)))
in favor of justforkJoin(args).pipe(map(r => [x, ...r]))
because it's more efficient and does basically the same thing.ObservableInput
rather thanObservable
. The code always supported Promise, Iterable, AsyncIterable, etc, but the TypeScript typings prevented it.PR Checklist

Other information
This is a refactor with the exception of type changes. Sort of a drive-by on my part because someone pointed me to this operator during an interview. If y'all want to add type changes or have someone take this PR over and run with it, that's fine.
I made this PR with the GitHub online IDE. I have no idea if CI will pass.
