Made worse by the fact that you really should check the type assertion first:

hvm, ok := di.TypeUnion.(xenlight.DomainBuildInfoTypeUnionHvm)
if !ok {
        //error
}

Right. If we wanted to make it easier on the users of the package, we *could*
add getters that hides the type assertion. But, that's still an extra step versus C.
