predefined variables : 
- inventory_hostname (fqdn) (normally the same as ansible.fqdn)
- inventory_hostname_short 

To know the return codes returned by ansible modules, just use plain ansible -vvv to see them : 
ansible -i ~/ansible/arrfab.net/hosts/hosts.cfg -vvv -m copy -a 'src=files/sysinfo dest=/etc/sysinfo' tungstene.arrfab.net
tungstene.arrfab.net | success >> {
    "changed": true,

## One line per log entry with merge graph
## (--decorate is implicit for newer git versions?):
#git log --graph --oneline --decorate

## Add --branches --remotes --tags --merges to see entries for all of the
## corresponding refs, not only commits (--all for all refs).

## Format output with --pretty=tformat:'<format>'
## Interesting placeholders for oneline <format>:

// Тайпкласс Animal (для полноты картины добавил метод hello, иначе был бы совсем тривиальный пример)
// Animal полностью абстрагирован от низлежашего типа A
trait Animal[A] {
  def word: String
  def talk() { println(word) }
  def hello(a: A): String
}
 
// Обертка над тайпклассом Animal, чтобы можно было писать cat.hello, а не animal.hello(cat)
// AnimalOps полностью дублирует методы, определённые в Animal, но также может содержать еще и дополнительные методы.
