I don't think so! any object can receive messages, even the unnamed ones.
It's' enough the object be referred by the one who wants to send the message to
it,
for example having an slot pointing to it. (sorry it's' my english again :.)), I
mean
The object who wants to send a message should have an slot pointing to the
unnamed
object. This way you can send messages without problems...

For example, the objects of the parser "mango" have no name. See in
globals-applications.

Well Jose, i am a beginner too. Some things belong to the "philosophy field of
implementation". I guess it's because of the searching in the object tree,
if you want the object be available all over the world you must put it in
an accessible way in the searching path. Just like Smalltalk, a class or global
variable must be in the Smalltalk dictionary, the difference is that it's
automatically
made when you create the class. <<Someone correct me if i'm wrong...>>.

May be someone else could help us in this field!
