Iteration order over maps is random - see 
http://blog.golang.org/go-maps-in-action 

doc: "When iterating over a map with a range loop, the iteration order is not 
specified and is not guaranteed to be the same from one iteration to the next"

I'm 99% certain that fmt.Println uses a

for x,y in range map 

to iterate over a maps elements eg see package fmt documentation and code ie 
http://golang.org/src/pkg/fmt/print.go?s=7070:7117#L885

99% certain not a liteide issue. 

(however current Go release 1.12 does seem to output in order)
