overload in classfile can't run

[luoliwoshang]

Is it expected that the overloaded function defined in classfile is not recognized as overload

over.gox

func addString(a, b string) string {
    return a + b
}

func add = (
    func(a, b int) int {
        return a + b
    }
    addString
)

main.gop

ov := &over{}
println ov.add__0(1, 1) // 2
println ov.addString("1", "1") // 11

// println ov.add(1, 1) // got error

Expected result

2
11
2

Got

$ gop run .
main.gop:5:9: ov.add undefined (type *over has no field or method add)
