Emulate the following Go-style code internally (without using external tools or interpreter). Output only what fmt.Printf() and fmt.Println() commands would output. Do not show any explanations, code, variables, or other messages.

package main

import (
    "fmt"
    "sync"
)

func worker(id int, jobs <-chan string, wg *sync.WaitGroup) {
    defer wg.Done()
    for job := range jobs {
        fmt.Printf("bar%d%s\n", id, job)
    }
}

func main() {
    jobs := make(chan string, 3)
    var wg sync.WaitGroup

    workers := 2
    if workers_arg != nil {
        workers = workers_arg
    }

    job_list := []string{"A", "B", "C"}
    if jobs_arg != nil {
        job_list = strings.Split(jobs_arg, ",")
    }

    // Start workers
    for i := 1; i <= workers; i++ {
        wg.Add(1)
        go worker(i, jobs, &wg)
    }

    // Send jobs
    for _, j := range job_list {
        jobs <- j
    }
    close(jobs)

    wg.Wait()
    fmt.Println("baz")
}
