I think we have a similar way of thinking. I once wrote a blog post about a for loop extension (based on Golang for illustration) [0].
values := []string{"hello", "world"}
for v, value := range values {
fmt.Printf("%s", value);
}
inter {
fmt.Printf(",")
}
before {
fmt.Printf("[")
}
after {
fmt.Println("]")
}
empty {
fmt.Println("(nothing found)")
}
