R6 objects are basically just environments, so they're probably pretty
simple to save and restore (I haven't tested it out, though).

Ross,
Ah I didn't think about Smalltalk. Doesn't surprise me that they supported
upgrades of this sort. That aside I think the question is whether it's
realistic for a language like R to support such a mechanism automatically.
Smalltalk and Erlang both have tight semantics that would be hard to

Ross,
This is generally a hard problem in software systems. The only language I know
that explicitly addresses it is Erlang. Ultimately you need a system upgrade
process, which defines how to update the data in your system to match a new
version of the system. You could do this by writing a scr
I saved objects that were defined using several reference classes.
Later I modified the definition of reference classes a bit, creating new
functions and deleting old ones. The total number of functions did not
change. When I read them back I could only access some of the original
data.
