    "sister": "Susan",
    "brother": "Louis",
}
format.Printf("%<brother>s loves %<sister>s.", params)

Tips

Named variable can be reused.

var params = map[string]interface{}{
    "sister": "Susan",
    "brother": "Louis",
}
format.Printf("%<brother>s loves %<sister>s. %<sister>s also loves %<brother>s.", params)
