I can just copy the code out of gnus-registry.el and abstract the
functionality to do a first cut of such a library. For a large
hashtable, though, converting to a list on the way in and out is
inefficient compared to storing it in a more "native" format. Is there
such a format, comparable to the native list read-eval format, as seen
in gnus-load:
(with-temp-buffer
(insert-file-contents file)
(while (not (eobp))
(condition-case type
(let ((form (read (current-buffer))))
(eval form))
;; ... much code omitted ...
cc to emacs-devel as I think this is of interest to that list.
Thanks
Ted
