Hmm. What is the application for? How would you model it as a bunch of interacting \
objects? Can you give a short user story for the application you are trying to \
create?


What is making you feel uncomfortable about having a class for the parameters? What \
would make you feel comfortable instead?

I usually get a feeling of discomfort when the code is fighting me. The solution is \
to think about responsibilities.

Usually the class that owns a parameter is the best place to put the responsibility \
of dealing with it. If you have classes that are constantly asking others for info \
then the responsibilities are probably in the wrong place. 

Hth,

Yours in curiosity and service, --Jerome Peace
