Thinking about your comment, we may find useful a #at:ifAbsent: message 
or something like that. Just to check if a preference already exist.

*Note.* To created or update a preference you don't need to check its 
existence:

    /Modus Operendi//
    //- To create a Preference, invoke the instance creation class
    method (Preference name:description:category:type:value:). The new
    preference is automatically remembered. If a preference with same
    name already exist, its instance is updated with the new provided
    data and its instance returned./

    PreferenceNG comment


As I am going to use PreferenceNG for the numerous DrGeo preference, I 
will learn how to more appropriately extend a bit the protocol.
