Yes...

There's an example: plt/collects/mzscheme/tree.cxx       with
                    plt/collects/mzscheme/tree-finish.ss

But it looks like I never documented `make-primitive-class' from
"class.ss", and much of the glue code in "tree.cxx" is probably
mysterious. I'll work on those sometime soon.
