Yes, see the POD docs for the Xapian module, e.g.:

perldoc Xapian

In particular the COMPATIBILITY section should answer all your questions
about stringification changes.

(I have just pushed a fix for the misformatting of code snippets
containing `>`).

There's also technical background as to what blocks us implementing
stringification when using SWIG (at least currently) here:

https://github.com/swig/swig/issues/1771

As I mentioned there, longer term I'm hoping to add back stringification
to our SWIG-generated perl bindings, but have it consistently call
get_description() for all objects which have such a method.

Yes, I used the get_termname() function and it worked like a charm, 
almost.? Actually that gave me the answer I needed but the loop kept 
quitting with a SEGV.? I tracked it down the the overloaded ++.? When I 
replaced $xit++ with $xit->inc() it kept running.? Guess there's more 
than one problem with overloading.

Thanks,

Jim.
