Async/Await for Swift

Proposal: SE-XXXX
Authors: Chris Lattner, Joe Groff

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.

1.同一台电脑可以有2个git账号（不同网站的）

首先不同网站，当然可以使用同一个邮箱，比如我的github，gitlab，bitbucket的账号都是monkeysuzie[at]gmail.com 这时候不用担心密钥的问题，因为这些网站push pull 认证的唯一性的是邮箱比如我的windows 上 2个账号一个gitlab 一个github （用的都是id_rsa）

host github
  hostname github.com
  Port 22

host gitlab.zjut.com
