Yes. It is an utility function the "dataholder module" shall provide to 
all subclasses. (Well, in this case I decided to move the loader method 
into the base class itself 'cause it will be used very often, but there 
are lots of other utility classes, like a debugger, I'd prefer to separate.)

Yes, I see. I found an example like this when I was looking around for 
inspiration ;) last week, but your explanation helped me to realize that 
this should be the right way for my case, too. ;)

Thanks again, that was very helpful to see the thing's a bit clearer. :)
