Please consider posting it as a message here on SFTALK. The expanded
conversation would be nice.

But please note that I have implemented an object model which can do all
or most of these functions already, and it will be incorporated into the
next major release of SwiftForth.

The implementation of an object model in SwiftForth is not trivial, at
least if you want the objects to be executable in saved turnkey applications
or (especially) in a callable DLL. The relocation issues are paramount and
must be carefully considered and implemented. A model that will run in
just the load/interpreter/debug environment is much easier, but has only
limited usefulness as a product enhancement.
