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: sorter.go
    path of file: ./repos/joker/core/gen_go
    
    the code of the file until where you have to start completion: package gen_go

// Implements the SortValues() function, used primarily to stabilize
// (and, in some cases, ensure correct operation of) traversal of maps
// when generating code.

// NOTE: This code comes from github.com/jcburley/go-spew (originally davecgh/go-spew):

import (
	"bytes"
	"fmt"
	"io"
	"reflect"
	"sort"
)

// catchPanic handles any panics that might occur during the handleMethods
// calls.
func catchPanic(w io.Writer, v reflect.Value) {
    
func handleMethods(w io.Writer, v reflect.Value) (handled bool) {
	// We need an interface to check if the type implements the error or
	// Stringer interface.  However, the reflect package won't give us an
	// interface on certain things like unexported struct fields in order
	// to enforce visibility rules.  We use unsafe, when it's available,
	// to bypass these restrictions since this package does not mutate the
	// values.
	if !v.CanInterface() {
		v = UnsafeReflectValue(v)
	}

	// Choose whether or not to do error and Stringer interface lookups against
	// the base type or a pointer to the base type depending on settings.
	// Technically calling one of these methods with a pointer receiver can
	// mutate the value, however, types which choose to satisify an error or
	// Stringer interface with a pointer receiver should not be mutating their
	// state inside these interface methods.
	if !v.CanAddr() {
		v = UnsafeReflectValue(v)
	}
	if v.CanAddr() {
		v = v.Addr()
	}

	// Is it an error or Stringer?
	switch iface := v.Interface().(type) {
	case error:
		defer catchPanic(w, v)
		w.Write([]byte(iface.Error()))
		return true

	case fmt.Stringer:
		defer catchPanic(w, v)
		w.Write([]byte(iface.String()))
		return true
	}
	return false
}
