Luciano,

There are many ways to do namespaces.

Perhaps the simplest is to have multiple #symbol hashmaps.

You probably know that 'someSring' as always yields the same symbol.
See #Symbol class>>intern:

Having a uniq hashmap for each namespace gives multiple symbols with the 
same spelling -- one per namespace.

This has also been used for multiple versions of code.  Useful when 
debugging a new version of the debugger -- just use the old, working 
code to debug the new.

The tools need to display symbols with some font/annotation so that you 
know to which namespace a symbol belongs, Code Browser needs to add 
methods using selectors in the proper namespace and so on.  Much 
confusing otherwise.
