I agree on that.  But I think Sven was talking about something a 
bit different from executing a script, namely interactive work at 
the console. I believe the question is: should interactive work in 
the gui program (by point and click or via console commands) be 
treated as a single "thread", or should there be a distinct 
"console thread", with its own notion of "last model"?

Personally, I'm not sure about this, but I have tripped over the 
issue myself once or twice.  E.g. estimate a model in the gui, 
open the console, type "genr uh = $uhat", and get an error message 
because there's no $uhat available...
