go - Identify non builtin-types using reflect

Question

I need to differentiate such types as

type A []byte

from a []byte. Using reflect, reflect.TypeOf(A{}).Kind tells me that it is a Slice of byte. How can I differentiate []byte{} from A{}, without having a bounded list of types to check for?

Are there new ways to do it in newer versions of Go?
