  Modules are a bit of a hack for historical
reasons. In practice it isn't much of a problem.
- Actions and rules are accessed in the same way.
  Thus, actions can be called from other modules.
- Targets refer to the file system which is
  global. Scoping them by module would be
- Most variables shouldn't be accessed from
  other modules anyway.
