How to sort struct with multiple sort parameters?

Question

I have an array/slice of members:

type Member struct {
    Id int
    LastName string
    FirstName string
}

var members []Member

Another pattern, which I find slightly cleaner:

if members[i].LastName != members[j].LastName {
    return members[i].LastName < members[j].LastName
}

return members[i].FirstName < members[j].FirstName
