[Cuis-dev] Do classes know what package they come from ?

[Nicola Mingotti]

Thank you Gerald,

I did the digging, I see that `MyClass package` works "top down",
from the PackageList down. Not bottom up.

It is not an issue for my use case. I am not going to change it.

I just thought the Class system worked as tree structure so, doing
something like 'MyClass father father` would bring me up to the package 
level.
I see my supposition was wrong ;)

bye
Nicola
