	if typ == nil {
		panic("reflect: Zero(nil)")
	}
	t := typ.(rawType)

	switch t.Kind() {
	case Func, Chan, Map, Ptr, Slice, UnsafePointer, Interface:
		return Value{t, nil, valueFlagExported}
	case Bool, Int, Int8, Int16, Int32,Int64, Uint,Uint8,Uint16,Uint32,Uint64,Float32,
		Float64, Complex64, Complex128, String, Array, Struct:
		val := alloc(typ.Size(), nil)
		return Value{t, val, valueFlagExported&valueFlagIndirect}
	default:
