Hi Stephane,

thank you for replying to me. I think I should have left out the 
middle part of my post regarding references to Smalltalk, I just 
thought that there has to be access to it, maybe it would be better to 
replace all hardwired refs to it with something like 'Smalltalk 
default' in order to prepare Squeak for multiple environments, maybe 
something else, I don't know. 

However, you don't convince me really on finding things in additional 
classes.

At first you have to find Imports. Probably you need some more 
dictionaries holding data, if you don't want to have this data in 
Smalltalk. Isn't this more complicated than to have one single place 
where to look for this? Wasn't Smalltalk meant to be the single place 
for this?

Again I must say you can't use senders of, references to, because you 
don't know a selector or a class name, and class name searches with 
guessing parts of the name is not easy. Especially because you have to 
know beforehand that there is such data referenced by such a class.
