hwow - for the stupid (me):
@@x seems to be the same thing for the whole inheritance-hierarchy (or
whatever this thing is called)... but i thought every class has it's very
own class-vars....
i mean... what's the purpose of that? hmmm. i did never notice this. i guess
it just seems so strange due to me not being familiar with it this way...
and - am i right? - in java it would say ABC, wouldn't it?
strange...
