Raman @ 2012-07-31 15:42 UTC (permalink / raw) To: emacs-devel, Jonathan Yavner Hi, At present, ses.el defines its all its internal accessors as macros -- could we please have them changed to use defsubst? Would help Emacspeak out in that the emacspeak ses extension would compile cleanly and be less error prone. For now, I've cloned the macros and redefined them as defsubst in the emacspeak namespace, but I'd like to avoid having to do that long-term. -- -- ^ permalink raw reply [flat|nested] 3+ messages in thread

I have some local changes which do that and a few more things, but I haven't cleaned it up and some of the changes are probably not appropriate. It might be a good starting point for someone to extract the defstruct part.
