>> from PA import A, ..... <whatever you need>

I am only using dtml and not writing directly python code !
So I do not believe this is possible.

>> Almost unbelievable.

But true.
But I will have again to do some test. 
(I do not have the time right now, and I did most of my
test with the previous version of Zope)

What I will have to do:
- create a Package (Zope product).
- create a class in this package, and a method (my_method)
- create another package.
- create a class in this package that inherits the class of the other
package.

- check that the method my_method is visible from within the second package.
