That basically is a vote for global objects. Whether they are accessed 
through a global variable or some sort of getter function that returns 
access, it means bypassing the parameters. Well from what I read here, 
there are no strong opinions for either concept. Strange, I wasn't able 
to find good arguments for or against the two concepts anywhere, I guess 
they are just used interchangeably in applications.

Personally I am for global objects since they keep the interfaces 
smaller and avoid tramp data, the problem I see is just the unit test 
setup. Subprograms with side effect are hard to test automatically
