go - if语句的多重赋值

Question

是否可以通过if条件执行多次赋值，如下面的代码？

func SendEmail(url, email string) (string, error) {

    genUri := buildUri()
    if err := setRedisIdentity(genUri, email); err != nil; genUrl, err := buildActivateUrl(url, genUri);  {
        return "", err
    }  

    return "test", nil

}

看起来你想要这样的东西:

package main

import "fmt"

func a(int) int { return 7 }

func b(int) int { return 42 }

func main() {
    if x, y := a(1), b(2); x > 0 && x < y {
        fmt.Println("sometimes")
    }
    fmt.Println("always")
}

输出:

sometimes
always
