Not a good reason.  I just only updated one version of the wrapper.

Ideally, the Search::Xapian::Database methods would be automatically
inherited by Search::Xapian::WritableDatabase, but that doesn't seem to
happen.  I don't know if this is just how XS works, or if we're doing
something wrong.

I'm hoping we can move Search::Xapian to use SWIG at some point, but
that needs SWIG to support "directors" for Perl, which is doesn't yet.
There is a somewhat dated patch though.

Yes, that would be handy.  A small regression test would be useful
too (assuming there's one for Database, just repeating that for
WritableDatabase would be fine.

That's the way to do it, unless we can persuade it to inherit.
