Bug#24047 proposes changing Elisp's 'signal' function to not return. Although this has been the documented behavior for decades, apparently there has been a back door in 'signal' for nearly as long, which causes 'signal' to return sometimes under control of the Elisp debugger. The proposal is to remove this backdoor. If this proposed change to Emacs would cause problems for you, please send email to address@hidden Thanks.
