**I actually managed to set a header:**
```
package main
import (
"fmt"
"encoding/json"
)
func PrettyPrint(v interface{}) (err error) {
b, err := json.MarshalIndent(v, "", " ")
if err == nil {
fmt.Println(string(b))
}
return
}
func Main(inobj map[string]interface{}) map[string]interface{} {
fmt.Println("inobj:")
PrettyPrint(inobj)
// set headers
headers := make(map[string]interface{})
headers["kek"] = "kok"
headers_bin_str,err := json.Marshal(headers)
headers_str := string(headers_bin_str)
if err != nil {
fmt.Println(err)
}
// assemble response
outobj := make(map[string]interface{})
fmt.Println(headers_str)
header_map := make(map[string]string)
header_map["headername"]= "headerval"
outobj["headers"] = header_map
outobj["statusCode"] = 201
outobj["body"] = "123"
fmt.Println("outobj:")
PrettyPrint(outobj)
return outobj
}
```
I hereby request to extend the documentation with a nice example.
