missing type in composite literal

[Tong Sun]

Hi, 

I don't know how to fix this "missing type in composite literal" problem. 

Here is the code (http://play.golang.org/p/l1Loj7M9n4):

package main

import "fmt"

type Room struct {

numOfLamps int

}

type Livingroom struct {

Room

items map[string]int

}

func main() {

r := Room{5}

pr := &r

l := Livingroom{*pr, {"sofa": 2, "chair": 4}}

fmt.Printf("%#v\n", l)

}

please help. 

Thanks

Add a type for items:

type Items map[string]int

Then use it in the literal:

l := Livingroom{*pr, Items{"sofa": 2, "chair": 4}}

Thanks Peter, 

I know adding a type for items will work, but the problem is, what's the proper way to do it without adding that extra type?

Specify the real type: map[string]int{"foo": 42}
