摘要：
在Haskell中，异步IO和并行执行是提高程序性能和响应速度的关键技术。本文将围绕Haskell语言的异步IO，特别是使用concurrently库进行并行执行与结果收集的实例，展开详细的技术解析，旨在帮助开发者更好地理解和应用这些技术。
一、
Haskell作为一种纯函数式编程语言，以其强大的并发和并行处理能力而著称。在处理大量数据或复杂计算时，异步IO和并行执行能够显著提升程序的执行效率。本文将深入探讨Haskell中的异步IO和concurrently库的使用，并通过实例展示如何实现并行执行与结果收集。
二、Haskell中的异步IO
在Haskell中，异步IO是通过使用`IO`类型和`async`库来实现的。`IO`类型代表异步操作，而`async`库提供了创建异步任务和等待它们完成的功能。
三、concurrently库简介
`concurrently`库是Haskell中一个强大的并行执行工具，它允许开发者轻松地将多个异步任务并行执行，并收集它们的结果。该库基于`async`和`async-wait`库，提供了简洁的API来管理并行任务。
四、安装concurrently库
在Haskell中，可以使用`cabal`或`stack`工具来安装`concurrently`库。以下是一个使用`cabal`安装的示例：
bash
cabal install concurrently
五、并行执行与结果收集实例
以下是一个使用`concurrently`库进行并行执行与结果收集的实例：
