It would be very cool to add the ability to use alternatives in the glob and match patterns.

Syntax of alternatives can be any:

• (alt1|alt2|alt3)
• (alt1,alt2,alt3)
• {alt1|alt2|alt3}
• {alt1,alt2,alt3}

Please look at code example:

package main

import (
	"fmt"
	"path/filepath"
)

func main() {
	fmt.Println(filepath.Match("/home/dir/*.(txt,pdf)", "/home/dir/resume.txt"))
	fmt.Println(filepath.Match("/home/dir/*.(txt,pdf)", "/home/dir/resume.png"))
}

Output:

true <nil>
false <nil>

I apologize if I'm suggesting something that has already been suggested. As it seemed to me, I looked for references, but did not find.
