On the other hand: If one would use the metaclass provided by my patch ALL
OVER THE PLACE in Sage, then one could solve #8119 by simply starting the
rename() method by calling `hash(self)`. Then, the hash would be computed
and cached before renaming, and thus the cached hash value would not
change when renaming.
However, applying the metaclass everywhere is probably a very bad idea.
The intention of this ticket really is to just provide a new
'''optional''' feature.
