how to set environment variables on google appengine?

Question

I'm trying to set and use an environment variable on google app engine. My app.yaml file looks as below. However when I use os.Getenv("mytoken") I get an empty string instead the actual value I set. Is it a GAE bug?

api_version: go1
handlers:
- url: /.*
  script: _go_app
env_variables:
  mytoken: '88786d9b9a0359824'

The feature is now documented here. However, as I have tested just now, it doesn't work on AppEngine. It does work on local server, so don't be fooled..

Edit: It works on Google AppEngine. My previous failure is due to a mistake. Consider this:

import "os"

var consumer = OAuth1Consumer{
    secret: os.Getenv("secret")
}

It does not work if you declare as global variable.
