Question(Pipeline): Should run `onLast` with same context with other middlewares?

[tqma113]

const createCurrentCounter = (hooks: Hooks, onLast?: (input: I) => O) => {
    return createCounter<I, O>((index, input, next) => {
      if (index >= middlewares.length) {
        if (onLast) return onLast(input)
        throw new Error(`Expect returning a value, but all middlewares just calling next()`)
      }

      const middleware = middlewares[index]
      const result = runHooks(() => middleware(input, next), hooks)

      return result
    })
  }

All middlewares run with runHooks but the onLast is not, is it a feature or could improve?

It could be improved as an opt-in feature when calling pipeline.run(context, options)

[tqma113]

Emm, why is it a opt-in feature? I think it could a default feautre? It also not affects the code written before.

[tqma113]

Just like this.

runHooks(() => onLast(input), hooks)

[Lucifier129]

Yes, it can be a default setting, I mean we should offer an option to enable or disable.
