It's just to have a concept of namespaces -- in a large policy
configuration there's a good chance that symbol names (for variables,
functions etc) would collide. The module and export statements allow you
to control how much pollution you cause in other modules. Also it's much
nicer if you don't have to think all the time about whether a symbol
name might already exist in another module.
