I have a simple map. Previously it was:
- declared at the module level,
- created in main using make at runtime, and then
- initialized with a series of assignments.
Now I initialize it all at once with a single block of data, but to do this I need two map variables: one at the module level and one in main.
Am I missing something, or is this just the way of Go?

Why not initialize it directly at the package level, if that’s the desired end result?

and here is a slightly more Go-idiomatic solution, defining a type Roman int
implementing the Stringer
interface:
http://play.golang.org/p/ocjkvshRfK
so the main
function looks like:
func main() {
rom1 := RomanFrom("CXXIII")
rom2 := RomanFrom("CCCXXI")
fmt.Printf("%v + %v = %v\n", rom1, rom2, rom1+rom2)
}

I tried using an equal sign in six different places, apparently all wrong. Who knew Go would be so picky?

you may want to follow the go-tour:
https://tour.golang.org
map literals are explained there: https://tour.golang.org/moretypes/17
the tour is just a couple of hours for somebody already knowledgeable in programming.

I tried the tour. I quickly tired of it. I find programming exercises more enlightening. Stupid syntax errors keep tripping me up.
