Why use parameters? It's a way to set a 'sane default' to the parameters in the class back to the value that's in the foo::params class. If you want to override what's set in foo::params, just pass it in the class declaration. If you want to use the default value in foo::params, just declare the class by doing 'include <class>' and NOT pass any parameters.
