// prints `Hello Joe       '
mapprint.Printf("Hello %-10user!", map[string]string{
    "user": "Joe",
})
// prints `Hello    Joe    '
mapprint.Printf("Hello |-10user!", map[string]string{
    "user": "Joe",
})
// prints `Hello Joe, your balance is 0000104.00€!'
mapprint.Printf("Hello %Name, your balance is %010.2Balance€!", map[string]interface{}{
    "Name": "Joe",
    "Balance": 104,

// maybe something more exotic?
// prints `Hello Joe, your balance is ABAB104.00€!'
mapprint.Printf("Hello %Name, your balance is %AB10.2Balance€!", map[string]interface{}{
