As I have added the GBoxed entries to maps, Glib::CodeGen is creating
gperl_register_boxed() entries in register.xsh, but with NULL for the
wrapper class. If I understand the Glib::xsapi correctly, this means
the GBoxed gets a standard wrapper - which is what? Do I need to
change this? If so, how?

Thanks for this, and for the code to bless the hash.

Exactly right. Thanks.
