For a http ‘listenAndServe’ and ‘listener.close’, then it will trigger listener with this err “use of closed network connection”
I linked the issue, and there are example codes. I’m not sure how to solve this err in an elegant way.

### What version of Go are you using (`go version`)?
<pre>
go 1.18.0
</pre>
### Source codes
```shell
package main
import (
"net"
"net/http"
"time"
)
func main() {
listener, err := net.Listen("tcp", net.JoinHostPort("0.0.0.0", "0"))
if nil!=err{
panic(err)
}
httpServer := &http.Server{}
go func() {
err :=httpServer.Serve(listener)
if nil!=err && err!=http.ErrServerClosed && err!=net.ErrClosed{
panic(err)
}
}()
time.Sleep(time.Second)
err = listener.Close()
if nil!=err{
panic(err)
}
time.Sleep(time.Second)
}
```
### Error
```shell
panic: accept tcp [::]:64309: use of closed network connection
goroutine 6 [running]:
main.main.func1()
.../main.go:19 +0xb3
created by main.main
.../main.go:16 +0x15a
exit status 2
```
### Question：
Is that a right situation with this panic? Why I close the listener the server got one error that not belong 'http.ErrServerClosed' ?
And What is the right way to handle this error?

your main control flow will first start the server (in separate go routine).
look waitgroup examples how to wait for other go routines to finnish.
