Thanks, I'll have to use the older ways...

Btw, is the XS Perl binding going to be updated for Database::size()?
Or is the SWIG binding the only way forward?

Fwiw, I also wrote about some issues I found with the SWIG binding
sometime back: https://trac.xapian.org/ticket/523#comment:13
(but I've worked around the issues and public-inbox supports both
SWIG and XS on FreeBSD systems)

I'm mainly on Debian 10, and there'll still be users on CentOS 7.x
for a while :<
