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: csv_native.go
    path of file: ./repos/joker/std/csv
    
    the code of the file until where you have to start completion: package csv

import (
	"encoding/csv"
	"io"
	"strings"

	. "github.com/candid82/joker/core"
)

func csvLazySeq(rdr *csv.Reader) *LazySeq {
	var c = func(args []Object) Object {
		t, err := rdr.Read()
		if err == io.EOF {
			return EmptyList
		}
		PanicOnErr(err)
		return NewConsSeq(MakeStringVector(t), csvLazySeq(rdr))
	}
	return NewLazySeq(Proc{Fn: c})
}

func csvSeqOpts(src Object, opts Map) Object {
	var rdr 
    
func csvSeqOpts(src Object, opts Map) Object {
	var rdr io.Reader
	switch src := src.(type) {
	case String:
		rdr = strings.NewReader(src.S)
	case io.Reader:
		rdr = src
	default:
		panic(RT.NewError("src must be a string or io.Reader"))
	}
	csvReader := csv.NewReader(rdr)
	csvReader.ReuseRecord = true
	if ok, c := opts.Get(MakeKeyword("comma")); ok {
		csvReader.Comma = EnsureObjectIsChar(c, "comma: %s").Ch
	}
	if ok, c := opts.Get(MakeKeyword("comment")); ok {
		csvReader.Comment = EnsureObjectIsChar(c, "comment: %s").Ch
	}
	if ok, c := opts.Get(MakeKeyword("fields-per-record")); ok {
