// * Usage example:
// * pool := sync.new_pool_processor({ callback: worker_cb })
// * //pool.work_on_items<string>(['a','b','c']) // TODO: vfmt and generics
// * pool.work_on_pointers(['a','b','c'].pointers())

// * return &SResult{ item.reverse() }

// * pool := sync.new_pool_processor({ callback: sprocess })

// * for x in pool.get_results<IResult>() {
// * // do stuff with x
// * for x in pool.get_results<SResult>() {
// * println('result: $x.s')
