Could that be provided at the top level, e.g. (let ((hash-table-print-separator "\\\n")) (format "%S" my-hash-table)) or in some other way? It would make large hashtable dumps like the ones from the new registry.el and gnus-registry.el much easier to read and debug. In the old gnus-registry.el I had special code to break up alists like that but it was slow so I'd rather ask Emacs to do it for me at the C level. Thanks Ted
