This is my belief too! Sorry if I have been unclear, but that was not the
point of my suggestion. What I wanted to know whether currently most
parents and elements were pickled by construction or by "class + data". If
they already are pickled by construction, then how C.parent_class and
C.element_class are pickled is mostly irrelevant, now and in the future,
since it is seldom used.
Thanks in any cases for you detailed analysis!

Let's see if someone else has some preference between the two
implementations.
Cheers,
Nicolas
