You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: exec.go
    path of file: ./repos/octant/vendor/k8s.io/client-go/third_party/forked/golang/template
    
    the code of the file until where you have to start completion: //This package is copied from Go library text/template.
//The original private functions indirect and printableValue
//are exported as public functions.
package template

import (
	"fmt"

    
func printableValue(v reflect.Value) (interface{}, bool) {
	if v.Kind() == reflect.Ptr {
		v, _ = indirect(v) // fmt.Fprint handles nil.
	}
	if !v.IsValid() {
		return "<no value>", true
	}

	if !v.Type().Implements(errorType) && !v.Type().Implements(fmtStringerType) {
		if v.CanAddr() && (reflect.PtrTo(v.Type()).Implements(errorType) || reflect.PtrTo(v.Type()).Implements(fmtStringerType)) {
			v = v.Addr()
		} else {
			switch v.Kind() {
			case reflect.Chan, reflect.Func:
				return nil, false
			}
		}
	}
	return v.Interface(), true
}
