Generic list of functions

[hallow dust]

I have the following class method:

or<T extends (() => any)[]>(rules: T): ReturnType<T[number]> {
  for (const rule of rules) {
    try {
      return this.call(rule);
    } catch (_) {
      continue;
    }
  }
  throw new Error("no rule matched");
}

I want it to work such that e.g. or([() => "a", () => 1]) would be of type string | number. Currently the inference is not working correctly and I'm just getting any.

Any ideas on getting this to work?

Note the functions don't actually return strings and numbers

It should work though.

declare function or<T extends (() => any)[]>(rules: T): ReturnType<T[number]>

const result = or([() => 'hello', () => 42])
//    ^? - const result: string | number

ah yeah I had the issue wrong it's something else
