The following program crashes with panic:

package main

import (
    "html/template"
    "io/ioutil"
)

func main() {
    t, err := template.New("foo").Parse(string(data))
    if err != nil {
        return
    }
    t.Execute(ioutil.Discard, nil)
}

var data = "{{.|. urlquery}}"
panic: unidentified node type in allIdents
