I can help out here: In order to serialize an object (in XOTcl, creating
a canonical script from a in-memory snapshot of the given object,
capable of creating an object and its dependencies with all the
shebang), [package require] the serializer package which comes with your
XOTcl distribution:

Class create C -slots {
   Attribute a1 -default aaa
} -set x 1

C create c1

package req xotcl::serializer

#
# this provides a new method to all ::xotcl::Object instances, i.e. all
# objects -> serialize():
#

c1 serialize

-> ::C create ::c1 -noinit \
        -set a1 aaa

the resulting script can be stored (e.g., in a tsv) and shared between
thread interps. in the target interp, simply [eval] the script.
