   True. I'm kind of leaning towards this solution myself as well as it 
seems the cleanest, with no rough edges to deal with.

   We could actually clear the .current-project variable when loading is 
done and have the project.current-project() rule error out if there is 
no 'current project' context. This might also flush out some other 
use-cases where we were depending on 'undefined behaviour'...

   If the user wants to 'glob' a folder at a later stage, he can always 
use the built-in GLOB rule or any of its wrapper rules from the path module.
