Yes, ofcourse I implement inheritance. Multiple inheritance is a tricky
thing to implement on the other hand, since many OOP operators are naturaly
implemented via recursion,in the sense that an operator of a particular
class calls the corresponding operator of its mother-class. This can only be
done if there is a well-defined (=>unique) mother-class. A friend did notice
nevertheless, that my code is compatible with the notion of
"friend-classes", namely classes that offer methods to a given object
without actualy being ancestors for that object's class. I will limit my
ambitions to that for now, as I am pressed to release a beta version of the
package in a reasonable amount of time. If things go well, I will seriously
consider multiple inheritance as a feature to be realised in a future
