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: ident_test.go
    path of file: ./repos/cosmos-sdk/depinject/internal/codegen
    
    the code of the file until where you have to start completion: package codegen

import (
	"go/parser"
	"go/token"
	"testing"

	"gotest.tools/v3/assert"
)

func TestReservedIdents(t *testing.T) {
	const src = `
package mypkg

import "example.com/bar"

type MyInt int

var myVar int

func Build(a, a2 int, b string) (c int, err error) {}
`
	file, err := parser.ParseFile(token.NewFileSet(), "", src, 0)
	assert.NilError(t, err)

	fileGen, err := NewFileGen(file, "example.com/mypkg")
	assert.NilError(t, err)
	funcGen := fileGen.PatchFuncDecl("Build")
	assert.Assert(t, funcGen != nil)

	// go keywords get a suffix
	assert.Equal(t, "type2", funcGen.CreateIdent("type").Name)
	assert.Equal(t, "package2", funcGen.CreateIdent("package").Name)
	assert.Equal(t, "goto2", funcGen.Creat
