Proposal: Add named return into functions

There's this thing that I found recently, about returning named values (variables), for example:
import (
"fmt"
"net/url"
"path"
)
// Instead of
func URLGetFilename(rawURL string) (string, error) {
parsedURL, err := url.Parse(rawURL)
if err != nil {
return rawURL, err
}
return path.Base(parsedURL.Path), nil
}
// It's possible to do
func URLGetFilename(rawURL string) (parsedURL string, err error) {
obj, err := url.Parse(rawURL)
if err != nil {
return
}
parsedURL = path.Base(obj.Path)
return
}Just a silly example to demonstrate the existence of it.
