Hi Luciano, Juan,

Was busy elsewhere.

What I proposed imply one or more dictionaries per application. We can 
make it explicit. Note however, as Juan emphasized, it will not solve 
the problem of purging the system from zombies preferences.

I will emphasis how the Pharo implementation based on Pragma solves 
elegantly the problem:

The methods (decorated with the ad-hoc pragma) defining the preferences 
are removed when the application package is unload, so do the 
application preferences. There is nothing to clean up. What I like less, 
it is a bit complex.
