Please provide any additional information below.

f() always returns nil. g() always returns the err from h(). Both functions
should behave the same way.

func f() (err os.Error) {
    if n, err := h(); err == nil {
        fmt.Println(n)
    }   
    return
}

func g() (err os.Error) {
    n, err := h() 
    if err == nil {
        fmt.Println(n)
    }   
    return
}

Isn't this a duplicate of issue #377: := can shadow named return variables (and others)
