Ok, I understand your issue. But unfortunately, I don't know any good way how to do it in Gambas. In C++ there are private inheritance that solves the problem, but Gambas only has public inheritance.
Maybe Benoit can find out some way how to inherit only "some" of the symbols from a base class, if many Gambas programmers want that, and disallow such an inherited object to be cast to an ancestor class? /Emil 2012/2/11 Fabián Flores Vadell <fabianfloresvad...@gmail.com> > 2012/2/10 Emil Lenngren <emil.lenng...@gmail.com> > > > So what you want is to extend the array class with some extra methods? > > Just use > > Inherits Person[] > > in the PersonList class ;) > > > > Did you read the code and comments? > > Not at all.
