After the CPS / nested-let story I forgot about the zipper dict.

But is it really necessary?  The semantics is no longer needed:
problem solved with nested reps -- it was only used for locals.

So, I've closed the abstraction: there is now only:

    d-open      ;; create a new dictionary
    d-compile   ;; compile an instruction
    d-start     ;; start new definition
    d->forms    ;; close dictionary and output forms in order
