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: statement.go
    path of file: ./repos/goby/vendor/github.com/dave/jennifer/jen
    
    the code of the file until where you have to start completion: package jen

import (
	"bytes"
	"fmt"
	"go/format"
	"io"
)

// Statement represents a simple list of code items. When rendered the items
// are separated by spaces.
type Statement []Code

func newStatement() *Statement {
	return &Statement{}
}

// Clone makes a copy of the Statement, so furth
    
func (s *Statement) Render(writer io.Writer) error {
	f := NewFile("")
	buf := &bytes.Buffer{}
	if err := s.render(f, buf, nil); err != nil {
		return err
	}
	b, err := format.Source(buf.Bytes())
	if err != nil {
		return fmt.Errorf("Error %s while formatting source:\n%s", err, buf.String())
	}
	if _, err := writer.Write(b); err != nil {
		return err
	}
	return nil
}
