If I can throw in my two cents, you should really try to remove this 
limitation of Mozart. This is a real pain in the ass when you want to 
know what happens in a space (I used to need that in Mozart for 
debugging or statistics). In Mozart it is possible to use a hack in 
order to have side effects out of a space (ie modifiy state outside the 
space)  by using ports.
I think a design which would allow it would be much more Pythonic (we 
are between consenting adults :-)

Best,
