[go-nuts] Return value mismatch

Hi guys!

I have a weird problem. At least, I'm not used to see this happening in
other languages, so hence my question :)

I have a function, which returns a *[]interface{}*, and in the end of that
function, if the slice is empty, I would like instead to return *nil*. The
problem is, I'm not getting *nil* in the caller function. I'm placing
example code:

func getChildren(paramStuff string) []interface{} {
    var values []interface{}
    // Do Stuff
    if len(values) == 0 {
       fmt.Println("Returning nil")
       return nil
    }
    return values
}

func stuff() {
    fmt.Printf("%+v", getChildren("params"))
}

The output of this code, is:



*Returning nil[]*I was expecting to have *nil* as a return value, instead
of an empty array. Is this expected behaviour?

Thanks!
