The user didn't want to rewrite the code to alter some conditionals, and instead wanted Emacs to be changed so that they didn't have to do that. I pointed out that the user can trivially just pre-process the data if they didn't want to rewrite those conditionals. (And they can just modify the structure in place if GC's a concern.) I think the conclusion here is that we don't want to add :empty-object to json.c, so I'm closing this bug report. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
