Don't Do That Then.

Re-design the modules so that inheritance is a hierarchy.  A band-aid
solution may be to create a new class that mediates between two others,
breaking the circle.  Much better is to figure out why the classes need
to know so much about each other, and redesign them with smaller,
simpler interfaces.

Even if there were a way to do circular inheritance, it would be a
nightmare to understand, so needs to be redesigned anyway.
