Are type aliases handled correctly: aliased []int and a function returning a nil slice? #936

The following code produces different results between go and gopherjs. It seems that an empty array is returned instead of nil, and comparison fails.

package main

import (
	"fmt"
)

type intList []int

func Test() []int {
	return nil
}

func main() {
	var s1 intList = Test()
	var s2 []int = Test()
	
	fmt.Println(s1 == nil, s2 == nil)
	fmt.Printf("%#v %#v", s1, s2)
}
