A Tour of Go Map literals continued

package main 

import "fmt"

type Vertex struct {
    Lat, Long float64
}
var m = map[string]Vertex {
    "Bell Labs": {40.68433,-74.39967},
    "Google": {37.42202, -122.08408},
}
func main() {
    var m2 map[int]uint8
    m2 = make(map[int]uint8)
    m2[12] = uint8(12)
    m2[1] = uint8(1)
    fmt.Println(m)
    fmt.Println(m2)
