I'm writing some code, and I need it to catch the arguments and pass them through fmt.Println (I want its default behaviour, to write arguments separated by spaces and followed by a newline). However it takes []interface {} but flag.Args() returns a []string. Here's the code example

package main

import (
    "fmt"
    "flag"
)

func main() {
    flag.Parse()
    fmt.Println(flag.Args()...)
}

This returns the following error:

./example.go:10: cannot use args (type []string) as type []interface {} in function argument

Is this a bug? Shouldn't fmt.Println take any array? By the way, I've also tried to do this:

var args = []interface{}(flag.Args())

but I get the following error:

cannot convert flag.Args() (type []string) to type []interface {}

Is there a "Go" way to workaround this?
