Not sure what you mean by this question.  Both Python-written
classes (by implementing __iadd__) and extension types that are
written in C (by appropriate flags in their method tables) can do
in-place additions (&c).  What are 'extension classes'...?  Anyway,
this stuff is underdocumented, but, study the sources... it works.
