Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

go env Output

$ go env

What did you do?

package main

import (
"os"
"text/template"
)

func main() {
// Define a template.
const tmpl = this is a test {{.list[1]}}

// Prepare some data to insert into the template.

var UserList = []string{
	"aaaaa",
	"bbbbb",
	"ccccc",
	"ddddd",
}
td := map[string]interface{}{
	"name":    "test",
	"list":    UserList,
}


// Create a new template and parse the letter into it.
t := template.Must(template.New("tmpl").Parse(tmpl))

t.Execute(os.Stdout, td)

}

What did you expect to see?

i want : " this is a test bbbbb"

What did you see instead?

We don't use the issue tracker for questions. Please see https://golang.org/wiki/Questions.

In this case the problem is that the template language doesn't support indexing like [1].

I think what you want is https://play.golang.org/p/Xxn_ksCzWJL.
