Replying to [comment:9 roed]:
> I somewhat prefer using `sage.structure.factory.UniqueFactory` rather
than `cached_function` for object creation. The benefits are that you get
better handling of duplicate keys, pickling and unpickling via the
factory.
That would indeed be nice, but I currently don't have the time resources
to implement it.
