Eieio is part of Emacs.  The Gnus registry is saved using
eieio-persistent.

This class is relatively new and was a bit buggy in the past, though.
In new Emacs versions it works reliably AFAICT.

Might also be interesting.

The Eieio approach has the advantage that (an) Emacs Lisp (object) is
saved as (an) Emacs Lisp (expression).  It is slow, however.
