Re: [Nmock-general] NMock and private/internal classes

So why are you hiding ParameterClass? If it's only accessible via Main, 
then the whole thing is packaged up in one and there's no point in being 
picky. If UnderTest is callable elsewhere then ParameterClass has to be 
visible anyway. If I wanted to be more controlled, I'd make 
ParameterClass an interface and publish that.
