Ciao Michele.

I have n classes wich share the same interface.
I then have a single class which add functionality to all the n classes,
using their interface.
The only way I see to make this single class inherith from the choosed nx
class is this one.

If there is a better approach, I can implement it.

Thank you for the answer,
Riccardo
