Comment:

 I'm afraid your patches won't actually work!

 First problem is that you need to make operator() virtual too (and ideally
 get_description()).

 However, Xapian::Stem (like many Xapian API classes) is just a wrapper
 around a reference counted pointer.  So although with your patches you can
 now subclass Xapian::Stem in Python, when you pass an instance of the
 subclass to Xapian API functions, your Python stemming code won't actually
 get called, even if you make the operator() virtual.

 This is all already covered by #186, so closing this ticket as a
 duplicate.
