Re: private keyword dont appear to do anything

Visibility modifiers like private, and public are to the module not the 
scope.

"Symbols with private visibility can only be accessed from within the 
same module."

This is how module based languages work, a bit more useful then to the 
scope approach IMO. An easy mistake to make.
