Just a cautious reminder from the module disaster:

back at OOPSLA one of the main points was to "never" put a packaging 
system into the base system again for all the reasons in the above 
discussion.

The ability of Ginsu and Monticello to deal with a semantic model 
without loading the code first still needs to know where the code 
originally came from. So how would a generic attributation of the 
standard file out format work?

Assuming you don't want to extend something like the timestamp method.
