Description

We should add the concept of back-references. It feels cumbersome to have to
manage them in application code while being able to specify other consistency
properties by simple keywords. I don't have a clear idea how to do this yet; we
need to come up with one first.

konzeptionelles Problem: InstrumentedSet-Instanzen können von mehr als einem Objekt gemeinsam benutzt werden. Eine Referenz aus einer solchen Sammlung müßte dann Rückreferenzen auf alle beteiligten Objekte implizieren. Wenn das referenzierte Objekt aber nur eine einfache Referenz der gleichen Rückreferenzklasse besitzt, gibt das einen Widerspruch.
