a brief answer is: yes, but not directly, ... we still have some other
issues on our todo-list, but I guess we should get that working
ASAP. So if you like to volunteer to help out, you're invited :)

ZV> Why should one need this ?

if I understand it correctly, that is merely the same we internally
use in order to copy an object (or class). Hopefully, you can merely
re-use the code from predefined.xotcl in the src dir used to copy/move
objects (Object instproc copy). You just would have to build a script
instead of copying, right?

In general any XOTcl feature should be accesible via introspection. If 
you run into problems, this might be a missing language feature...

btw, we also require the obj/class code introspection in order to
build a script that is shipped around in the mobile code system
