Ah, this explains why my code is not working with more recent
versions
of Leo anymore.
The suggestion to model edges as "intermediate" nodes is the most
natural
thing to try, but these intermediate nodes will be visible to the
user, on top
of the necessity for me to re-program the features simplified out of
the basic
code. I understand the design decision, but this means my project will
be
eventually bound to legacy versions of Leo, which may well mean I'll
very likely abandon it.
