List all environment variables in Go

env.go

package main

import (
  "os"
  "fmt"
)

func main() {
  for _, pair := range os.Environ() {
    fmt.Println(pair)
  }
}

This doesn't list all the environment variables. Only the env variables that are exported in that session are listed. Is there any way to list all the environment variables ?

@avnish30jn A process is "firewalled" from its parents and siblings. One process can have the same variable with a completely different value as another. A process only has access to its own envs (and the ones the parent exports). Were it not so, scripting would be... hell, in the worst way.
