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: path_value.go
    path of file: ./repos/awless/vendor/github.com/aws/aws-sdk-go/aws/awsutil
    
    the code of the file until where you have to start completion: package awsutil

import (
	"reflect"
	"regexp"
	"strconv"
	"strings"

	"github.com/jmespath/go-jmespath"
)

var indexRe = regexp.MustCompile(`(.+)\[(-?\d+)?\]$`)

// rValuesAtPath returns a slice of values found in value v. The values
// in v are explored recursively so all nested values are collected.
func rValuesAtPath(v interface{}, path string, createPath, caseSensitive, nilTerm bool) []reflect.Value {
	pathparts := strings.Split(path, "||")
	if len(pathparts) > 1 {
		for _, pathpart := range pathparts {
			vals := rValuesAtPath(v, pathpart, createPath, caseSensitive, ni
    
func setValue(dstVal reflect.Value, src interface{}) {
	if dstVal.Kind() == reflect.Ptr {
		dstVal = reflect.Indirect(dstVal)
	}
	srcVal := reflect.ValueOf(src)

	if !srcVal.IsValid() { // src is literal nil
		if dstVal.CanAddr() {
			// Convert to pointer so that pointer's value can be nil'ed
			//                     dstVal = dstVal.Addr()
		}
		dstVal.Set(reflect.Zero(dstVal.Type()))

	} else if srcVal.Kind() == reflect.Ptr {
