go - 不能在 Go 中使用 "go"作为变量名

Question

我觉得这有点奇怪，为什么这段代码不起作用？

  package main

  import "fmt"

  func main() {
     var i, j int = 1, 2
     k := 3
     c, python, go := true, false, false

     fmt.Println(i, j, k, c, python, go)
  }

抛出错误

   # command-line-arguments
   .\compile64.go:8:13: syntax error: unexpected go, expecting expression
   .\compile64.go:10:29: syntax error: unexpected go, expecting expression

但这有效!

   package main

   import "fmt"

   func main() {
      var i, j int = 1, 2
      k := 3
      c, python, goo := true, false, false

      fmt.Println(i, j, k, c, python, goo)
   }

“go”是Golang中的保留字吗？

是的，一个关键字:

break        default      func         interface    select
case         defer        go           map          struct
chan         else         goto         package      switch
const        fallthrough  if           range        type
continue     for          import       return       var
